Previous issue date: 2017-06-30 / A utiliza??o de materiais comp?sitos para a constru??o civil tem sido objeto de estudo acad?mico em universidades e centros de pesquisa no Brasil e no mundo. 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.
