Alternative Fine Aggregates to Produce Sustainable Self Compacting Concrete: A Review

Self-compacting concrete (SCC), because of its magnificent fresh and hardened properties, is widely used around the world. Continuous increase in construction activities lead to enormous depletion of exhaustible resources and now the industry is on the verge of recognising the worth of such limited exhaustible resources. The disposal of some waste products into the land, on the other hand, leads to environmental imbalance. As a result of these factors, the approach to sustainable construction is becoming more prominent. As a result, researchers have performed experimental investigations into the feasibility of alternative fine aggregates (AFA) as a replacement for river sand in order to promote sustainable development and safeguard the environment. This paper provides a comprehensive overview of alternate sand’s physical characteristics, as well as their impact on SCC’s fresh and hardened properties. The use of AFA contributes significantly to the reduction of environmental pollution by lowering carbon dioxide emissions. SCC production costs are also reduced by using alternative fines. As a result, this paper seeks to give useful and important information on the subject, as well as a platform for new scholars to conduct future SCC research.
