ESTUDO DA INFLUÊNCIA DA SUBSTITUIÇÃO PARCIAL DO CIMENTO POR RESÍDUOS DE CONSTRUÇÃO CIVIL NA RESISTÊNCIA MECÂNICA À COMPRESSÃO AXIAL DE ARGAMASSAS MISTAS

Abstract

Considering the volume of waste generated by the construction sector, the objective of this work was to verify the variation of mechanical resistance to axial compression in mixed mortars, with partial replacement of cement by Construction and Demolition Residue (RCD) and Precast Industry Residue (RIPM). The reference mortar was made with the trace 1:2:8 and the substitutions occurred at the levels of 5, 10 and 15%. The results showed satisfactory performance among the mixtures made with RCD, since at 63 days the three replacement levels of this residue became statistically equal to the reference trait.
