It was presented the mechanical-thermo-acoustic characterization of a block-making composite for use in civil construction, with cement, marble and/or granite, plaster, EPS, sand, obtained in order to reduce the cost of building a residence, contributing to the reduction of the housing deficit and to removing harmful and immeasurable waste from the environment. The blocks made from the composite material obtained had as main characteristics the low cost, good compressive strength, low thermal conductivity, good acoustic resistance, good aesthetics, versatility, easy manufacturing and assembly processes and fast curing process. The work brings a combined study of the mechanical, thermal and acoustic resistances of the composite designed with the marble and marble/granite residues. It is emphasized that, besides the characterization of the conceived and produced composite, rooms were built, which demonstrated the mechanical viability of the proposed material and the thermal and acoustic resistance tests were performed in prototypes instead of the study restricted to the models. Blocks were manufactured with filling of 500 ml empty PETS bottles. Using the blocks with an area of around 0.2m2, four rooms were built with an area of 7.8m² each. The study determined which is the most viable block in relation to the combination of mechanical, thermal and acoustic resistances.
