Previous issue date: 2015-02-05 / A utiliza??o de materiais comp?sitos para a constru??o civil tem sido tema de in?meros trabalhos cient?ficos no Brasil e no mundo. Um dos fatores que motivam essa busca ? o d?ficit habitacional que os pa?ses principalmente do terceiro mundo enfrentam. No Brasil 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 nos processos de obten??o de placas de granito e m?rmore, cimento, gesso, areia, EPS triturado e ?gua. Esses res?duos causam grandes danos ao meio ambiente e s?o jogados em aterros em grandes quantidades. O ineditismo do trabalho est? no estudo combinado t?rmico, mec?nico e ac?stica do comp?sito obtido, em situa??o real, de c?modos que fazem parte de uma habita??o experimental. Foram confeccionados diversos blocos a partir de composi??es variadas e foram efetuados testes preliminares de resist?ncia mec?nica e t?rmica, escolhendo-se a propor??o mais apropriada. Ser?o apresentados os processos de fabrica??o e montagem dos blocos produzidos, em n?mero de 500, para a fabrica??o de uma resid?ncia experimental. Estudou-se qual o tipo de bloco e de res?duo, m?rmore ou granito, apresentou-se mais vi?vel para o fim proposto. A resist?ncia mec?nica dos blocos produzidos esteve acima de 3,0 MPa. A resist?ncia t?rmica dos blocos foi comprovada pela diferen?a m?xima entre as paredes interna e externa dos c?modos edificados em torno 8,0 ?C. A absor??o ac?stica para o c?modo mais eficiente ficou em torno 31. Demonstrou-se a viabilidade de utiliza??o dos blocos fabricados com o material comp?sito proposto para a constru??o civil. / The use of composite materials for the construction industry has been the subject of numerous
scientific papers in Brazil and in the world.
One of the factors that motivate this quest is the
housing deficit that countries especially the third world face. In Brazil this deficit reaches
more than 6.5 million homes, around 12% of all US households
. This paper presents a
composite that was obtained from waste generated in processes for the production of granite
and marble slabs, cement, gypsum, sand, crushed EPS and water. These wastes cause great
damage to the environment and are thrown into landfi
lls in bulk. The novelty of the work is in
the combined study thermal, mechanical and acoustic composite obtained in real situation of
rooms that are part of an experimental housing. Many blocks were made from cement
compositions, plaster, foam, sand, marb
le and / or granite, preliminary tests of mechanical and
thermal resistance were made by choosing the most appropriate proportion. Will be given the
manufacturing processes and assembly units 500 units 10 x 80 x 28 cm produced for the
construction of an ex
perimental home. We studied what kind of block and residue, marble or
granite, made it more feasible for the intended purpose. The mechanical strength of the
produced blocks were above 3.0 MPa. The thermal resistance of the blocks was confirmed by
the maxi
mum temperature difference between the inner and outer walls of rooms built around
8.0 ? C. The sound absorption for optimal room was around 31%. Demonstrated the
feasibility of using the blocks manufactured with composite material proposed for
construction.
