Usage of fly ash and slag as supplementary cementitious materials in engineered cementitious composites (ECCs) – A Review

Abstract

Researchers evolved Engineered Cementitious Composite (ECC) in the Nineties, belong to the family of high-performance fibre-reinforced cementitious composites. ECC, additionally known as bendable concrete as a ductile alternative to conventional concrete. ECC requires a huge amount ofsupplementary cementitious material (fly ash), contributing to sustainable development. In this paper, a review of ECC studied with supplementary cementitious materialswhich includefly ash and slag. ECC has better tensile strength, ductility and durability properties than other kinds of fibre reinforced concrete (FRC). The results are primarily based on the properties of ECC with fly ash and slag. This paper affords an exhaustive overview of ECC with the aid ofincorporating fly ash and slag as supplementary cementitious substances. The impact of fly ash fineness, the calcium content of fly ash, fly ash content,and slagon various properties of ECC are taken into consideration. Also, I studiedthe effect on the strength of ECC with fly ash at increased temperature.
