| Resumo: | The marble industry generates a large amount of dust waste. These wastes do not have a proper management plan, as well as being highly contaminating the population surrounding the site of the deposits for these materials. To offer a solution, this article shows the results of the development of a brick-based marble powder to achieve sufficient compressive strength for the construction of masonry walls in low-rise housing. The experimental program includes 16 different dosages that varies the amount of cement, lime, and sand, and keep constant the marble powder. The program includes the compressive tests for 160 bricks, compressive tests for 3 small walls, validated adherence under compression tests for 3 small walls, and absorption tests for 48 bricks. The results of the test showed that the compression strength of the individual bricks and wall is 4.0 MPa y 1.9 MPa, respectively, and the absorption of the bricks is 21 %. These results of absorption, compression and adhesion are a first indicator of the feasibility of used these bricks for the construction of load-bearing walls in housing projects developed in areas of low seismic demands |
