An Exhaustive Review on The Development of The Role of Cementitious Supplementary Cementitious Material in Ductile Engineered Cementitious Composite (ECC)

Abstract

In recent years, worldwide, a newly developed composite with an assurance of high ductility and high matrix toughness named as Engineered Cementitious Composites (ECC) is started. It is a known fact that the manufacturing of ECC uses a higher amount of fly ash, contributing to sustainable development and reduction of carbon footprint. In this paper, a review of ECC with supplementary cementitious materials such as fly ash has been studied. ECC looks similar to ordinary Portland cement-based concrete, except that it can deform (or bend) under strain. Conventional concrete's lack of durability and failure under strain, both stemming from brittle behaviour, have been a pushing factor in the development of ECC. ECC has exclusive properties, such as tensile properties, ductile properties, durability properties higher than other types of fibre reinforced concrete. Different trail mixes of ECC with fly ash, fly ash cenosphere and various authors have used calcium content of fly ash. The results have been assessed based on the properties of ECC in the presence of fly ash. This paper presents an exhaustive review of ECC by incorporating fly ash as a cementitious material. The reports consider the effect of fly ash fineness and fly ash content on various properties of concrete. Also, the effect on strength and other parameters studied at high-temperature conditions.
