Estudo para o aproveitamento de resíduos pétreos de marmorarias, como agregados para concreto de cimento Portland

In this paper, it is presented a study for the utilization of marble shops waste (stone by-products) as aggregate of Portland cement concrete. First, the material were separated and classified by lithologic type. After that, they were mixed in a crusher, producing the required aggregates. Several te...

Several tests for technological characterization of the material were done, intending to evaluate the use of the material as aggregate. Some simulations of Portland cement concrete dosage were done with variation in fine and coarse aggregate composition, water/cement ratio and mortar percentage. The materials were submitted to uniaxial compression test at 7th, 14th and 28th days, showing similar resistances, around to 35 MPa, independent of the aggregate mix and concrete dosage.http://www.redalyc.org/articulo.oa?id=81011705010
