Um dos elementos motivadores ? o d?ficit habitacional que os pa?ses principalmente do terceiro mundo enfrentam. No Brasil, entre 2010 e 2014, esse d?ficit alcan?a mais de 6,5 milh?es de moradias, em torno de 12 % dos domic?lios do pa?s. Esse trabalho apresenta um comp?sito que foi obtido a partir de res?duos gerados na ind?stria da constru??o civil (brita e cer?mica), res?duos de vidro gerados pela ind?stria vidraceira e elementos comuns em materiais da constru??o, tais como cimento, areia e ?gua. Esses res?duos causam grandes danos ao meio ambiente e s?o jogados nos aterros em grandes quantidades. O trabalho foca no uso de tr?s res?duos para a obten??o o comp?sito e na fabrica??o de dois tipos de blocos, um maci?o usado para piso e um vazado para ser usado em fechamentos verticais em edifica??es, podendo ser utilizados como alvenaria estrutural ou de veda??o. Utilizou-se doze formula??es, sendo duas delas servindo refer?ncia denominadas formula??es Padr?es, e posteriormente foram selecionadas as seis de melhores resultados mec?nico, incluindo uma padr?o com Cimento, Areia M?dia e ?gua. As formula??es escolhidas foram caracterizadas, determinando-se as resist?ncias ? compress?o axial e diametral, a absor??o de ?gua por capilaridade e imers?o total, a densidade e as propriedades t?rmicas. Foram confeccionados blocos com duas das formula??es do comp?sito de melhores resultados gerais utilizando formas especialmente fabricadas para este fim. Os resultados mais expressivos do comp?sito foram obtidos para a resist?ncia mec?nica ? compress?o que atingiu valor superior a 13 Mpa, absor??o de ?gua com resultados inferior a 7,5 %, Densidade inferior a 2,5 g/cm?, Condutividade com valores pr?ximos a 5 W/m.K e Difusividade inferior a 4 mm?/s. Estes resultados permitem que o comp?sito possa ser utilizado tanto na fabrica??o de blocos para alvenaria de veda??o quanto estrutural, tornando-o mais vers?til na ind?stria da constru??o civil. / The use of composite materials for civil construction has been the object of academic study in universities and centers of research in Brazil and worldwide. One of the motivating factors is the housing deficit that the countries of the third world are facing. In Brazil, between 2010 and 2014, this deficit reaches more than 6.5 million homes, around 12% of the country's households. This work presents a composite that was obtained from waste generated in the construction industry (gravel and ceramics), glass waste generated by the glazing industry and common elements in construction materials, such as cement, sand and water. These wastes cause great damage to the environment and are disposed of in landfills in large quantities. The work focuses on the use of three residues to obtain the composite and in the manufacture of two types of blocks, a solid one used for floor and one to be used in vertical closings in buildings, being able to be used as structural masonry or of sealing. Twelve formulations were used, two of them serving reference denominated Standard formulations, and later were selected the six of better mechanical results, including a standard with Cement, Average Sand and water. The chosen formulations were characterized, determining the resistance to axial and diametrical compression, water absorption by capillarity and total immersion, density and thermal properties. Blocks were made with two of the best overall composite formulations using specially fabricated forms for this purpose. The most expressive results of the composite were obtained for the mechanical resistance to compression reaching a value higher than 13 MPa, absorption of water with results lower than 7.5 %, Density less than 2.5 g/cm?, Conductivity with values close to 5 W/m.K and diffusivity less than 4 mm?/s. These results allow the composite to be used both in the manufacture of structural and masonry blocks, making it more versatile in the construction industry.

PBF da Zona Norte de Natal. Para tanto, foi necess?rio um levantamento das origens dessa regi?o e de como ocorreu sua expans?o no contexto do desenvolvimento urbano local, considerando sua evolu??o demogr?fica, em especial, a partir da constru??o dos conjuntos habitacionais e loteamentos formais e informais. A partir da pesquisa de campo, composta de um piloto in loco com algumas fam?lias residentes, tornou-se poss?vel iniciar a an?lise das condi??es habitacionais que culminou em um estudo detalhado do Cadastro ?nico do governo federal (Cad?nico), em rela??o a 100% (cem por cento) dos benefici?rios do Programa Bolsa Fam?lia (PBF) de Natal, com informa??es qualitativas e quantitativas. A partir desse levantamento geral, fez-se um recorte contemplando apenas os benefici?rios residentes na Zona Norte da cidade. Para melhor compreender essa realidade, a pesquisa verificou o d?ficit habitacional brasileiro, considerando suas origens, contextos hist?ricos e os conceitos utilizados pelas seguintes institui??es: Funda??o Jo?o Pinheiro (FJP), Instituto Brasileiro de Geografia e Estat?stica (IBGE), Instituto de Pesquisa Econ?mica Aplicada (IPEA), al?m do Plano Local de Habita??o de Interesse Social (PLHIS) e do Programa das Na??es Unidas para os Assentamentos Humanos (UNHABITAT). Ademais, foram comparados os diversos conceitos de cidade e sua respectiva evolu??o, considerando a import?ncia do planejamento como instrumento de pol?ticas p?blicas necess?rias ?s a??es governamentais e pol?ticas permanentes de Estado. Aponta-se, como resultado, para a import?ncia da utiliza??o do Cadastro ?nico do governo federal como instrumento eficaz para mensurar as condi??es de habitabilidade dos munic?pios brasileiros. / This research aims to analyze the housing conditions and socioeconomic of beneficiaries of the Bolsa Fam?lia Program ? PBF of the North side of Natal city. For that, it is necessary a survey of this region's origins and how its expansion has occurred in the context of local urban development, considering demographic evolution, in particular, from the construction of housing complex and formal and informal allotments. From the field research, consisting of a pilot in loco with some households, it became possible to start the analysis of housing conditions that culminated with a detailed study of the Single Register form of the federal Government (Cad?nico), in relation to 100% (one hundred percent) of the beneficiaries of the Bolsa Familia program (PBF) of Natal city, with qualitative and quantitative information. From this general survey, a cut was done, contemplating only beneficiaries residing in the north of the city. To better understand this reality, the survey found the Brazilian housing deficit, considering its origins, historical contexts and concepts used by the following institutions: Jo?o Pinheiro Foundation (FJP), Brazilian Institute of Geography and Statistics (IBGE), Applied Economics Research Institute (IPEA), and Local Plan Housing of Social Interested (PLHIS) and the United Nations Centre for Human Settlements (UN-HABITAT). Furthermore, were compared the various concepts of city and its respective evolution, considering the importance of planning as an instrument of public policy necessary to governmental actions and permanent policy of State. As a result, there are a detach about the deficit and housing conditions in the city of Natal, mainly North Zone, pointing out the importance of using the Unified Register of the federal government as an effective tool to measure the living conditions of Brazilian municipalities.
