Em agosto de 2001 havia, no Brasil, sete fábricas de cimento com licença para o co-processamento de resíduos industriais em seus fornos, em substituição à matriz energética, e 14 outras em vias de adquiri-la. Há mais de cinco anos, a Companhia de Cimento Ribeirão Grande conta com efetiva participação de uma mistura (blend) de resíduos industriais de diferentes correntes no processo. O clínquer co-processado é hoje o componente principal do cimento portland da fábrica, o qual manteve resistências mecânicas à compressão às idades de 1, 3, 7 e 28 dias sempre acima dos limites normativos mínimos exigidos. Para atestar a imobilidade dos componentes inorgânicos incorporados ao clínquer, utilizaram-se ensaios microscópicos e análises químicas por espectrometria de absorção atômica e de raios X em clínqueres industriais não co-processados e co-processados; testes de lixiviação em cimentos de laboratório; química mineral por microssonda eletrônica e microscopia eletrônica de varredura em clínqueres dopados com Zn, V e Pb. Os resultados levaram, em linhas gerais, às seguintes considerações: - A microestrutura dos clínqueres co-processados manteve-se preservada com a introdução do blend no sistema. - As matérias-primas e o combustível fóssil respondem por boa parte dos elementos traços presentes no sistema. O blend introduz aporte extra dos elementos traços presentes na composição, enriquecendo seletivamente o clínquer co-processado. - Há, de maneira geral, compatibilidade grande dos elementos traços com o clínquer, mesmo de elementos voláteis como cádmio e mercúrio. Já cobalto e, principalmente, chumbo, são os que se mostraram menos compatíveis. - Nos clínqueres experimentais, alita incorporou preferencialmente zinco e chumbo, e belita, vanádio. - Não houve solubilização significativa de nenhum elemento de relevância ambiental dos cimentos, atestando sua retenção nos retículos cristalinos dos minerais formadores do clínquer portland. A qualidade ambiental do clínquer portland co-processado deve abranger sua propriedade de reter elementos traços em solução sólida, a manutenção da integridade das relações texturais, e a garantia da imobilidade de componentes tóxicos no produto final, através de um controle sistemático dos clínqueres e também dos cimentos. / In August 2001, in Brazil, there were seven cement plants with and an increasing number of others on the way to get the permit to co-processing, i.e. burning industrial wastes in their kilns as substitutes for fossil fuels. For over five years now the Companhia de Cimento Ribeirão Grande has counted on partial substitution of a blend of different waste streams for fossil fuels in the burning process. Co-processed clinker makes up today the main component of their Portland cement, which has shown mechanical strengths at 1, 3, 7 and 28 days permanently above standardized minimal limits. In order to assess the immobility of trace elements incorporated to the clinkers, a methodology was used which comprised carrying out microscopy and chemical analysis by atomic absorption and X-ray spectrometry of both conventional and co-processed clinkers, leaching tests on laboratory cements prepared with co-processed clinkers, mineral chemistry by electronic microprobe and scanning electronic microscopy on experimental clinkers doped with Zn, V and Pb. The results led to the following general statements: - Co-processed clinkers showed sound microstructure just like conventional clinkers. - Raw materials – limestone, clay and iron ore – and fossil fuels account a great deal for the amounts of trace elements involved in the burning process. According to its composition, the blend enriches selectively co-processed clinkers. - A general compatibility of trace elements – even highly volatile ones such as Cd and Hg – in clinker was observed. Co and especially Pb, however, were comparatively incompatible. - Alite of experimental clinkers incorporated preferentially Zn and Pb while belite incorporated V. - No elements showed any significant solubility from laboratory cements, thus attesting retention of environmentally relevant trace elements in the crystal lattice of clinker mineral phases. Co-processed Portland clinker must present environmental quality by retaining trace elements in solid solution, while being able to keep sound textural relationships, and guarantee immobility of toxic components on the final product. This should be attested through a systematic control of clinkers and also of cements.

A radiopacidade é um importante pré-requisito para materiais utilizados como base e forramento de restaurações, pois possibilita que o profissional identifique a presença do material e permita sua diferenciação com a estrutura dental adjacente. O objetivo desse estudo foi avaliar a radiopacidade de materiais indicados como base e forramento e comparar com a radiopacidade do esmalte, dentina e escala de alumínio. Para isso, foram analisadas 16 marcas comerciais de cimento de ionômero de vidro, 8 marcas de resina composta flow e 4 marcas de cimento de hidróxido de cálcio. Foram confeccionados três conjuntos de três corpos de prova de 4 mm de diâmetro, com espessuras de 1, 2 e 3 mm para cada cimento de ionômero de vidro e resina composta flow e de 1 mm para cada cimento de hidróxido de cálcio. Foram feitas secções transversais de coroas de três terceiros molares humanos para obtenção de espécimes de esmalte e dentina com espessura de 1, 2 e 3 mm. Como controle, uma escala de alumínio padrão com nove degraus de espessura foi utilizada. As tomadas radiográficas foram feitas com o sistema digital RVG 5000 Kodak (Kodak Company, França) e tempo de exposição de 0.32 segundos. As imagens obtidas foram trabalhadas no programa Image Tool® para obtenção dos valores médios de cinza. A análise estatística ANOVA, seguida pelo teste de Tukey (p0.05) detectou diferenças consideráveis entre os materiais da mesma categoria e entre as espessuras. Algumas marcas comerciais apresentaram radiopacidade inadequada segundo as normas ISO 4049 e 9917 (Ionomaster, Maxxion, Bioglass R, Bioglass F, Vidrion R e Vidrion F), apresentando radiopacidade inferior à da dentina, insuficiente para um correto diagnóstico. Todas as resinas compostas flow e cimentos de hidróxido de cálcio estudados apresentam radiopacidade superior a da dentina. As marcas comerciais Vitro Fil, Magic Glass, Vitrebond, Riva SC, Riva LC, Fill Magic, Opallis, Surefil Tetric N, Tetric, Hydro C, Hydcal e Liner apresentaram radiopacidade igual ou superior a do esmalte, em todas as espessuras. De um modo geral, o aumento de espessura dos materiais estudados aumenta significativamente sua radiopacidade. Conclui-se que existem materiais indicados como base e forramento de restaurações com radiopacidade inadequada para serem detectados radiograficamente. / Radiopacity is an important pre-requisite for base and liner materials, once it allows the professional to identify the presence of the material and makes its differentiation from the adjacent tooth structure possible. The aim of this study was to evaluate the radiopacity of liner and base materials and compare to the radiopacity of enamel, dentin and aluminum stepwedge. For this, 16 glass ionomer cements, 8 flowable resin composites and 4 calcium hydroxide cements were analysed. It was prepared three sets of three test specimens with 4 mm in diameter and thicknesses of 1, 2 and 3 mm for each glass ionomer cement and flowable composite and 1 mm for each calcium hydroxide cement. Cross sections were made from crowns of three third molars to obtain specimens of enamel and dentin with thickness of 1, 2 and 3 mm. As a control, a standard aluminum stepwedge with nine steps was used. Radiographs were taken with digital Kodak RVG 5000 (Kodak Company, France) and exposure time of 0.32 seconds. The images were analysed through the program Image Tool ® to obtain the mean grey values. Statistical test ANOVA followed by Tukey test (p 0.05) detected significant differences between the materials of the same category and between the thicknesses. The commercial brands Ionomaster, Maxxion, Bioglass R, Bioglass F, Vidrion R and Vidrion F, presented radiopacity lower than the radiopacity of dentin, insufficient for a correct diagnostic. All flowable resin composites and calcium hydroxide cements studied showed radiopacity superior than dentin. Vitro Fil, Magic Glass, Vitrebond, Riva SC, Riva LC, Fill Magic, Opallis, Surefil, Tetric N, Tetric, Hydro C, Hydcal and Liner showed radiopacity equal to or greater than the enamel for all thicknesses. In general, the increased thickness of the materials studied increases its radiopacity significantly. It was concluded that some materials indicated as base and liner for restorations have and inadequate radiopacity to be detected radiographically.

Degree Project Advanced Level - Business Administration, Linnaeus Business School at Linnaeus University, Business Process and Supply Chain Management, 4FE02E, Spring 2010.   Authors: Muhammad Rizwan ul Haque, Ahmed Nawaz Shaikh, Kamonmarn Jaenglom, Zaheer Tariq Tutor: Petra Andersson   Title: Supplier Selection Process Improvement through Six-Sigma DMAIC (A case of Lafarge Pakistan Cement Limited)   Background: Cement industry is considered to be an intensive supplier base industry. Cement manufacturing involves several types of suppliers ranging from general utilities to large plant equipments. Also, supply chain performance is significant topic in many cement organisations. The supply chain department at Lafarge Pakistan Cement Limited (LPCL) wants to inspect and improve their supplier selection process. The intended objective of this inspection is two folded. First, LPCL wants to develop a competitive supplier base out of bulk suppliers available in the market that would result in competitive advantage over its competitors. Second, they want to improve their supplier selection process so that there would be low variance and exclusion of unnecessary activities that would ultimately help in achieving the cost, quality and service enhancement objectives.   Research question: How can the existing supplier selection process at Lafarge Pakistan Cement Limited (LPCL) be improved by applying Six-Sigma DMAIC?   Methodology: This thesis is a descriptive case study and was conducted with a deductive approach. Data was collected through interviews, discussions and questionnaire. The scientific credibility of this thesis was secured by using many sources, avoidance of assumptions, studying a common process and following standardized steps of supplier selection. Conclusion: The existing process of supplier selection at LPCL was defined and mapped to understand the process characteristics and capabilities. The existing process was then analysed to identify problem areas, variations and unnecessary activities. Corrective actions were recommended to deal with problem areas and an improved supplier selection process for LPCL was suggested with process coordination and control measures. Suggestions for future research: Based on the findings of this thesis, we suggest that the further research for LPCL could be done in the area of sourcing and suppliers relationship management. Sourcing; a study could examine the sourcing policy at LPCL on purchasing practises of products. It would also be interesting to focus more on this area which leads to excellent cost reduction. Using scenario method could compare and analyse regional, national and worldwide sourcing. Supplier Relationship Management; a study could investigate supplier relationship management that leads to creating a competitive advantage for LPCL through the development of supplier performance monitoring and supplier development programme. More details could continuously move towards cost reduction, increased reliability and risk mitigation, transparency of supplier costs and quality, and enhanced efficiency of sourcing process.

Thesis (MTech. degree in Environmental Health)--Tshwane University of Technology, 2012. / Fall out dust sampling and monitoring is becoming one of the preferred methods to determine dust pollution impact from industries/or mines on the receiving environment. Fall out dust monitoring is a useful and cost effective method of providing trend analysis of dust deposition over a period of time. It also provides an indication of the main areas of dust generation and can be conducted for both health and nuisance purposes.The aim of the study was to develop a positioning guideline for fall out dust monitoring equipment in order to optimise the existing fall out dust programme.

The use of injectable biomaterials is growing as the demands for minimally invasive procedures, and more easily applicable implants become higher, but their availability is still limited due to the difficulties associated to their design. Each year, more than 700,000 vertebral compression fractures (VCF’s) are reported in the US and 500,000 VCF’s in Europe due to primary osteoporosis only. VCF’s can compromise the delicacy of the spinal canal and also cause back pain, which affects the patient’s quality of life. Vertebroplasty was developed in the 80’s, and has proven to be a safe minimally invasive procedure that can, quickly and sustainably, relieve the pain in patients experiencing VCF’s. However, biomaterials for vertebroplasty still have limitations. For instance, ceramic bone cements are difficult to distinguish from the bone using X-ray techniques. On the other hand, acrylic bone cements may cause adjacent vertebral fractures (AVF’s). Large clinical studies have indicated that 12 to 20% vertebroplasty recipients developed subsequent vertebral fractures, and that 41 to 67% of these, were AVF’s. This may be attributed to the load shifting and increased pressure on the adjacent endplates reached after vertebroplasty with stiff cements. The primary aim of this thesis was to develop better injectable biomaterials for spinal applications, particularly, bone cements for vertebroplasty. Water-soluble radiopacifiers were first investigated to enhance the radiopacity of resorbable ceramic cements. Additionally, different strategies to produce materials that mechanically comply with the surrounding tissues (low-modulus bone cements) were investigated. When a suitable low-modulus cement was produced, its performance was evaluated in both bovine bone, and human vertebra ex vivo models. In summary, strontium halides showed potential as water-soluble radiocontrast agents and could be used in resorbable calcium phosphates and other types of resorbable biomaterials. Conversely, linoleic acid-modified (low-modulus) cements appeared to be a promising alternative to currently available high-modulus cements. It was also shown that the influence of the cement properties on the strength and stiffness of a single vertebra depend upon the initial bone volume fraction, and that at low bone volume fractions, the initial mechanical properties of the vertebroplasty cement become more relevant. Finally, it was shown that vertebroplasty with low-modulus cements is biomechanically safe, and could become a recommended minimally invasive therapy in selected cases, especially for patients suffering from vertebral compression fractures due to osteoporosis.

Fracture to the neck of femur is frequently stabilised with a hip screw system, however the host bone is often weak or osteoporotic. This causes premature failure of the system, commonly by cut-out of the lag screw through the head of the femur. While augmentation of the fixation with bone cement improves the holding power and decreases failure rate, current methods of administering the cement are messy and inaccurate. This project proposes a lag screw design which allows for direct injection of the cement, via the lag screw itself, after the screw has been inserted and correctly positioned in the femur. A method is also suggested to reduce the risk of cement leakage into the joint space when the guide wire has punctured the head of the femur. The design uses a system of holes in the threaded section of a cannulated screw to allow delivery of cement to the desired area; the modified screw was also tested with and without the tip of the screw closed. These design and implantation techniques were compared to the standard design lag screw both with and without bone cement augmentation by traditional methods. Initial testing in a synthetic bone analogue looked promising. The modified screw with closed end performed better in push out tests than the standard screw alone and comparably with the standard screw with cement augmentation. A second phase of testing with the synthetic material was then conducted to more closely represent physiological loading conditions. In this case again the closed ended modified screw with cement augmentation outperformed the original screw and was comparable with the augmented original screw. However, during this phase of testing problems were observed with the synthetic testing material and it was decided to conduct further testing in paired porcine cadaveric femurs. Several further problems occurred in this phase of testing, including the bending of the test screws. It was concluded that the modified screw showed potential in being a more accurate and consistent method of cement augmentation, however neither the synthetic bone analogue or the porcine material was an adequate model of an osteoporotic human femur. If a suitable testing material could be found, continued study of this prototype may prove beneficial.

O cimento Portland (CP) é um produto industrializado que não é só consumidor de energia e de matérias-primas, mas também responsável por grandes emissões de CO2. Além do impacto ambiental, a presença de alguns compostos hidratados que em contato com os sulfatos, produzem fases expansivas que reduzem a vida útil das estruturas. Adições minerais, como as escórias de alto-forno, têm sido adicionadas para reduzir o clínquer e aumentar a resistência aos sulfatos, porém nem todas as escórias conferem empregabilidade como adição devido a sua composição química. Cimentos com adições apresentam ganho de resistência muito lento nas primeiras idades, tornando-se desinteressante para a cadeia produtiva da construção civil. Assim, as limitações que o CP apresenta, somada ao aumento dos resíduos, incentivaram a busca por aglomerantes isentos de clínquer. A álcali ativação proporcionou a possibilidade de reaproveitamento de diversos subprodutos, pois a cinética de reação é similar ao CP, devido à semelhança química e liberação de calor. Pesquisas ligadas à durabilidade dos cimentos álcali ativados (CAT) ainda são bastante reduzidas, principalmente a eficácia dos métodos empregados para avaliação da resistência aos sulfatos em ambientais laboratoriais. Portanto, este trabalho teve como objetivo investigar o comportamento das pastas de escórias ativadas com 5% de NaOH e CP resistente a sulfatos (CPIV-RS) em ambientes sulfatados através do método NIST e comparar com o método acelerado em argamassas proposto pela NBR 13583:2014. As avaliações incluíram as análises microestruturais (DRX/MEV/DTG) e macroestrutural através de inspeções visuais, variação dimensional, variação de massa e resistência à compressão. Os resultados indicaram que nas condições ensaiadas, os métodos acelerados de avaliação da resistência aos sulfatos não apresentaram diferenças significativas entre as pastas e argamassas. Os CATs apresentaram desempenho superior antes e depois da exposição ao Na2SO4 comparados aos CPIV-RS, favorecendo a hidratação e a resistência à compressão. Por outro lado, a formação da gipsita parece ser o principal produto de degradação dos CATs na solução de MgSO4, originado pela descalcificação do C-S-H, afetando fortemente as propriedades físicas, químicas e mecânicas dos cimentos álcali ativados. / Portland cement (PC) is an industrialized product that is not so consuming of energy and raw materials, but also responsible for large CO2 emissions. Besides the environmental impact, the presence of some hydrated compounds that in contact with the sulfates, produce expansive phases that reduce the useful life of the structures. Minerals additions, such as blast furnace slag, have been added to reduce clinker and increase resistance to sulphates, but not all slags confer employability as addition because of their chemical composition. Cements with additions show very low resistance gain in the early ages, making it uninteresting for the productive chain of civil construction. Thus, the limitations that PC presents, together with the increase of residues, have encouraged the search for clinker-free binders. Alkali-activation provided the possibility of reuse of several by-products, because the reaction kinetics is similar to PC, due to chemical similarity and heat release. Researches related to the durability of alkaliactivated cements (AAC) are still very low, mainly the efficacy of the methods used to evaluate the resistance to sulfates in laboratory environments. Therefore, the objective of this work was to investigate the behavior of slag pastes activated with 5% NaOH and sulfate resistant PC (PCIV-SR) in sulphated environments using the NIST method and to compare with the accelerated mortar method proposed by NBR 13583:2014. The evaluations included microstructural analysis (XRD/SEM/DTG) and macrostructural analysis through visual inspection, dimensional variation, mass variation and compressive strength. The results indicated that under the conditions tested, the accelerated methods of sulfate resistance evaluation did not present significant differences between pastes and mortars. The AACs presented better performance before and after exposure to Na2SO4 compared to PCPIV-SR, favoring hydration and compressive strength. On the other hand, the formation of gypsum appears to be the main degradation product of the AACs in the MgSO4 solution, caused by the C-S-H decalcification, strongly affecting the physical, chemical and mechanical properties of the activated alkali cements.

Additives have been developed to generate flexible pastes with mechanical resistance capable to support the expansions and retractions of the metallic covering of the wells that submit to the steam injection, technique very used to increase the recovery factor in oil reservoirs with high viscosity. A fresh paste with inadequate rheological behavior may commit the cementation process seriously, involving flaws that affect the performance of the paste substantially in the hardened state. This work proposes the elaboration and the rheological analysis of Portland cement pastes with addition of residues of rubber tire in several proportions, with the aim of minimizing the damages provoked in the hem cementing of these wells. By thermogravimetric analysis, the particles of eraser that go by the sieve of 0,5mm (35 mesh) opening and treated superficially with NaOH solution of 1 mol/L presented appropriate thermal resistance for wells that submit to thermal cyclic. The evaluation of the study based on the results of the rheological analysis of the pastes, complemented by the mechanical analysis, thickening, stability, tenor of free water and filtrate loss, being used as parameter a paste reference, without rubber addition. The results showed satisfactory rheology, passive of few corrections; considerable loss of mechanical resistance (traction and compression), compensated by earnings of tenacity, however with established limits for its application in oil wells; satisfactory stability, free water and thickening time / A baixa tenacidade apresentada pelas pastas de cimentos Portland utilizadas na cimenta??o de po?os de petr?leo tem motivado v?rias pesquisas voltadas para materiais alternativos.

However, the cement sheath is constantly under mechanical stresses and temperature variations caused by the recovery of heavy oil. In order to minimize fracture and wear of the cement sheath, new admixtures are developed to improve the properties of Portland cement slurries and avoid environmental contamination caused by leaking gas and oil. Polymers with the ability to form polymeric films are candidates to improve the properties of hardened cement slurries, especially their fracture energy. The present study aimed at evaluating the effect of the addition of a chitosan suspension on cement slurries in order to improve the properties of the cement and increase its performance on heavy oil recovery. Chitosan was dissolved in acetic ac id (0.25 M and 2 M) and added to the formulation of the slurries in different concentrations. SEM analyses confirmed the formation of polymeric films in the cementitious matrix. Strength tests showed higher fracture energy compared to slurries without the addition of chitosan. The formation of the polymeric films also reduced the permeability of the slurry. Therefore, chitosan suspensions can be potentially used as cementing admixtures for heavy oil well applications / A cimenta??o prim?ria ? uma das principais opera??es na perfura??o do po?o de petr?leo.

This thesis is focused to the ideal concept, design, implementation and em-placement of a sculpture in the respective area, designed in a deeper context of the work itself to its surroundings, its history and specific local character. To solve the emplacement of the sculpture, a scenic park surrounding the Castle at Štěkeň (South-West Bohemia) has been chosen. The design respects fully not only scenic dominants, but also neighboring architecture and vistas directly in the respective locality. A full appeal of the art work is enabled by applying convenient material re-specting its milieu and the sculpture theme itself as well. Also the onlooker´s position toward the sculpture proportions and its comprehensibility and readability has been taken in consideration. The theme and concept of the sculpture is closely connected to the Christian Or-der ?Congregatio Jesu? settled directly in the facilities of the Štěkeň Castle and related first of all to Mary Ward, its founder and to her first community of ?English Virgins? as well. A component part of this thesis is formed by a secondary pedagogic project ? a workhop meeting for children, convened in autumn 2010 directly to the Štěkeň Castle premises. It dealt with the human being´s relation to the landscape. This thesis focused to the relation between an art work and the surrounding sce-nery is concerned also to spiritual creativity from the point of view of actual cultural-social neediness respecting also the application and readability of Christian symbolism in respect to actual cultural experience.
