Sustainable and Greener Self-Compacting Concrete incorporating Industrial By-Products: A Review

Abstract

This paper presents an extensive critical review of various properties of self-compacting concrete made with industrial by-products. The construction industry has recognized the worth of limited available natural resource like river sand, which is extensively used for the production of self-compacting concrete. Also, the management and disposal of the industrial by-products has become a major challenge globally. Sustainable production thus comes into picture by incorporating the industrial by-products in self-compacting concrete to benefit the environment as well as concrete technology. This paper highlights the use of industrial by-products like waste foundry sand, coal bottom ash, waste tire rubber, copper slag, and waste glass as fine aggregate replacement in the development of green self-compacting concrete. It discusses in detail, the physical and chemical properties of industrial by-products used in self-compacting concrete. It comprehensively reviews the effect of using by-products on the fresh, strength and durability properties of self-compacting concrete. Based on the reviewed literature, critical analysis has been carried out, and the future scope of work is addressed. These industrial by-products have a great potential to be utilized in self-compacting concrete, leading to sustainable development.
