REUTILIZAÇÃO DE AREIA DE FUNDIÇÃO EM ARGAMASSAS

Abstract

Foundry sand is a solid residue from the metallurgical industry and is generated from the unmold stage of metal parts. The objective of this study is to evaluate the incorporation of this sand residue as a fine aggregate in mortars. The substitution of natural sand for the residue resulted in twelve mortar traces. Tests of consistency, mass density, water absorption by capillarity and compression resistance were carried out. The tests showed that the foundry sand can be used as a partial replacement of natural sand by considering the influence of the residue fineness modulus on the mortar final properties.
