Reviewing the potential of waste paper incorporation in enhancing concrete sustainability

Abstract

Abstract Concrete is made from a mix of aggregate, sand, water, and cement. Waste Paper Concrete (WPC) is a mix of concrete and Waste Paper (WP). Every year, WP production slowly goes up. Because of this, more space is needed for disposal sites, which use energy, use up natural resources, and make the world dirtier. By using WP in concrete, pollution in the environment could be cut down. So, this review paper looks at what can be done with WP by replacing fine aggregate, coarse aggregate, and cement in concrete at 0%, 5%, 10%, 15%, and 20%. This study talks about the physical and chemical properties of the WP. This study also looks at the fresh, mechanical, and structural characteristics of WPC, like slump, modulus of elasticity and stress-strain relation. Based on this review, the fresh, mechanical, and structural characteristics of concrete improve when WP is added at 5% and 10%, but they get worse when WP is added at more than 10%. The SEM shows that there are some pieces of wet cement. When adding 10% WP, the hydrated cement particles are inclined to improve the strength of the concrete more than when adding 5% WP. It’s clear that adding WP to regular concrete, which doesn’t have any waste paper in it, gives it a lot of good qualities that regular concrete doesn’t have. By improving its properties and efficiency, WP could have the right qualities to be used in making concrete.
