Contribution to the development of a lightweight concrete based on recycled waste paper

Abstract

This work presents a study on a building material named papercrete which is a type of fibrous concrete made by shredding paper as pulp in water, with Portland cement and local sands (river and dune sand). The percent of waste paper used (10%, 20%, 30%, 40% and 50%) by weight of sand. The mechanical properties studied of the mixtures are compressive strength and flexural strength. Results showed that increasing the content of waste paper, decreases the compressive strength. However, the flexural strength is increased with content of paper up to 20%, then decrease for high percentages of paper
