NMR is gaining increasing interest in civil engineering for applications regarding microstructure characterization as e.g., to determine pore sizes or to monitor moisture transport in porous materials. This study reveals the capability of NMR as a tool for pore size characterization. Therefore, we measured floor screed and synthetic materials at partial and full saturation. For most examined materials, the pore size distribution was successfully determined using either a reference or a calibration method. Since diffusion effects were observed for some samples in single-sided NMR measurements, further tests employing an NMR core analyzer were carried out in a homogeneous magnetic field. The finally obtained surface relaxivity of floor screed (50 μm/s) resulted to be much higher than suggested by literature.

Nowadays the attention to the utilization of secondary raw materials as a component of building materials is being paid to in the Czech Republic and in the world. This thesis deals with possibilities of using secondary raw materials as partial cement substitutes in industrial floors. The aim of this thesis is to verify the influence of cement substitution amount with secondary raw materials and their fineness of grinding on the properties of the floor surface in time and on its structure. On the basis of the acquired knowledge, the influence of the pre-treatment of the secondary raw material on the properties of the floor ceiling with an emphasis on the economic aspect was assessed. After evaluating the results, some substitution of cement in the floor screed with secondary raw materials is beneficial. The significant influence of more intensive milling of the floor screeds base on the parameters of the final floor screed was not confirmed. It seems, that it is possible to achieve very good results even when using secondary raw materials with a lower percentage of fine particles. This brings together the economic benefits of lowering the cost of a lower dose of expensive cement by using cheaper secondary raw materials, because pre-treatment of such materials does not require the use of a large amount of energy.

The trend in today's civil engineering are growing demands for quality and comfort constructed buildings and spaces in them. This trend causes a change in the approach to designing buildings and building new buildings. One of the main directions great importance is attached dedicated reconstruction of buildings and their technical adjustments to meet the ever increasing demands being norms and laws. One of the most monitored parameters are thermal-technical characteristics of objects - i.e. better quality means saving on heating costs. In this connection there is a big trend of the modern construction industry and building insulation, mainly ETICS systems. Dissertation focuses on the basic (reinforced) layer of the ETICS and examines the effect of low temperatures, acting on the matter in the implementation of the system, the properties of this layer. This coating is one of the key elements of the system, which more or less determines the quality and durability of the system. The first part deals with the current state of the problem and generally insulation systems, basic types and the advantages and disadvantages of these systems. In the main part of the work is solution focused work, its objectives and methodology for testing materials using laboratory tests and are mentioned outputs of experiments in terms of results. The final section addresses the evaluation of the data and results and output for construction practice. The theme of work was also addressed in the specific research. The works are also numerical and graphical attachments to records of experiments and calculations.

Denna rapport är resultatet av ett examensarbete som utförts isamarbete med byggföretaget K360 i Uppsala. De arbetar medkakling av badrum i renovering och nybyggnation. En fallstudiehar besvarat forskningsfrågan “Hur kan byggföretag i Sverigegenom materialval och arbetssätt i samband med kakling avbadrum, minska sina koldioxidutsläpp och sin användning avfarliga ämnen?”. Materialen avser avjämningsmassa, fästmassa ochkakel. Litteraturstudierna bygger på rapporter och skrifter frånstatliga institutioner, kommuner, företag och tidningsartiklar. Dettycks saknas forskning om avjämning och fästmassa. Litteraturenberör klimatneutral betong, farliga ämnen, avfallshantering ochföretagskultur och visar följande. Cementen i betong ger högakoldioxidutsläpp. I klimatneutral betong har delar av cementenbytts ut mot bl.a. flygaska. Den gör att betongen eller avjämningentorkar långsamt. Cementindustrin forskar på metoder för attminska sina koldioxidutsläpp. En annan studie bygger på en teoriatt normaltorkande avjämning möjliggör klimatneutraltbetongbjälklag då den fungerar som fukt- och alkalispärr. Denempiriska studien beräknas färdig 2021. Farliga ämnen skaminskas och mycket farliga ämnen ska fasas ut. Dessa ärcancerframkallande, hormonstörande, svårnedbrytbara, kraftigtallergiframkallande och förändrande av arvsmassa ellerfortplantning. Försiktighetsprincipen bör tillämpas då det saknasforskning om många ämnens miljöpåverkan i kombination medandra. I cementbaserade fästmassor och avjämningsmassor kan detfinnas plasttillsatser som medför giftiga biocider. Det finnsnaturliga alternativ. Avfall bör i första hand minimeras, sedanåteranvändas, materialåtervinnas, energiutvinnas och sistdeponeras. I K360s miljöpolicy står att de värnar ommedarbetarnas delaktighet. Litteraturen stödjer delaktighet ochyrkesstolthet som drivkraft till ett företags kvalitetsutveckling därmiljö är en del. Beslut ska baseras på fakta som kräverkommunikation men K360 saknar idag forum för miljö- ochklimatfrågor. Sju kvalitativa intervjuer har genomförts medplattsättare och projektledare. Alla intervjuade anser att miljö- ochklimatfrågor är viktigt. Samtliga plattsättare strävar efter attminska spillet genom planering och beräkning av materialåtgång.Detta blir lättare med mer erfarenhet. För att effektivt kunnaanvända kakelplattorna krävs tid för planering och logiskttänkande. Tidsbrist, standarden för att kapa kakelplattor, mått ochutformning av badrummen utgör hinder för att förebygga spill.Möjligheterna för detsamma är att i projekteringsstadiet anpassatidsplan, badrummets mått och kakel. Allt material återvinns närmöjlighet ges. Beställarens krav och pris styr materialvalet. Andrafaktorer är låg vikt och att det fungerar med befintliga material.Plattsättare och projektledare uttrycker tilltro till att materialet ärkontrollerat för farliga ämnen. Överlag saknar de kunskap ommaterialens innehåll och möjligheten att påverka materialvaletupplevs vara litet. En produktjämförelse jämför fästmassornaCentro FK# 1000 som K360 använder mycket och Haga 325 Bio-Platten- und Fliesenkleber. Produkterna är likvärdiga ochcementbaserade. Centros innehåller plasttillsatser medan Hagasbara naturliga tillsatser. Diskussionen tar upp om ett riktatlitteratursökande kan ha lett till att källor missats och att källorfrån företag kan vara vinklat. Hänvisningar från kommunen ochoberoende källor stärker informationen. Vidare diskuteras omtilliten hos informanterna till materialkontrollerna är frånsägandeav ansvar men flera uttalanden pekar på starkt ansvarskännande.Slutsatsen från produktjämförelsen är att ett byte från Centro tillHaga skulle minska potentiellt farliga ämnen. Andra slutsatsersom dras är att det saknas klimatneutral avjämningsmassa påmarknaden men det kan komma att visa sig att normaltorkandeavjämning är att föredra. Företaget saknar idag forum för internkommunikation om miljöfrågor vilket gör att information fastnarhos enskilda individer. Rapporten rekommenderar K360 att avsättaresurser för att uppdatera sig om materialinnehåll ochmiljöutveckling, skapa forum och vägar för intern kunskaps- ocherfarenhetsöverföring, sprida information om material ocharbetssätt till beställare och producenter av material, fortsätta medcementbaserad avjämning och byta mot klimatneutral cement iframtiden.
