PHYSICAL AND MECHANICAL ANALYSIS OF THE RECOVERY OF GRANITE PÉTREOS WASTE AS ADDED GRAFTING IN PORTLAND CEMENT CONCRETE

Abstract

The increase in waste generated by the construction industry (RCC) in recent years, without adequate disposal, has accumulated concerns not only to government agencies but also to the environment and public health in Brazil, which varies from region to region. region. The use of these RCCs incorporated in concrete to reduce these clusters has been a solution increasingly employed by companies in this segment that are concerned with the future of our. Therefore, this study presents a feasibility in the use of marbled residues as a large aggregate in total replacement of crushed stone No. 0 in conventional concrete. For this, laboratory experiments were carried out with the objective of characterizing all the materials used. After the characterization, the axial compressive strengths of the hardened and cured Test Bodies were verified in the ages of 7 and 28 days, divided in two groups with 4 CPs each. The average of the results of the residue with a value of 25.02 MPa and the conventional concrete with gravel, of 27.32 MPa, makes it possible to use the residue for small buildings such as: sidewalks, gutters and small non-structural slabs bearing.
