RCH ARTICLE OPEN ACCESS PHYSICAL AND MECHANICAL ANALYSIS OF THE RECOVERY OF GRANITE PÉTREOS WASTE AS ADDED GRAFTING IN PORTLAND CEMENT CONCRETE
-
Descrição
-
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.
Keywords: Concrete. Granite residue. Use.
