Resí­duos de papel autoadesivo como substitutivo parcial da areia em concreto e argamassa de cimento

Abstract

One of society's great challenges is to seek alternatives for the use of waste generated in its activities. The research aimed to evaluate the feasibility of using selfadhesive paper waste as a partial substitute for sand in concrete blocks and cement mortar. The methodology adopted used stages of making concrete blocks and cement mortar, and testing their main physical properties in the hardened state, namely, compressive strength and water absorption, at the ages of 7, 14, 21 and 28 days. Between the two products researched, the concrete obtained is stable, indicating a feasibility of partial replacement of sand by self-adhesive paper, which allows the use of this material in small works.
