Cementitious Materials Usage in Self-Compacting Concrete: A Review

There are significant changes observed in concrete materials, the properties of innovated concrete have also experiencing revolutionize through hi-tech encroachment. Instead of new changes in the materials used in concrete making, the adjustment in concrete is started from conventional concrete strength and slowly tracked by high-strength concrete and high-performance concrete. Recently, the exploitation of by-products waste in the self-compacting concrete (SCC) had achieved massive interest among researchers due to practicable and beneficial features. Most of the prior works focused on SCC combining with supplementary cementitious materials such as fly ash, coal bottom ash, silica fume, ground granulated glass blast-furnace slag and rice husk ash. Concrete with these cementitious materials have been used extensively throughout the world. These materials used as mineral admixtures in concrete and strengthen the durability and concrete properties. The concrete applications are increasing with the passage of time due to their superior structural performance, environmental friendliness and low impact on energy utilization. Through these understanding, this research points out the idea of cementitious materials in concrete, especially SCC possess with numerous positive features such as durability, flowability and overall performance of concrete. It can be seen that cementitious materials have high benefit and lead to curing potential. However, it is important to understand that these materials are relatively expensive. Thus, this is a main reason behind their less adoption compared to add as mixtures in Portland cement.
