Effect of Supplementary Cementitious Materials on Compressive Strength of Engineered Cementitious Composites: A Review

Abstract

AbstractEngineered Cementitious Composites (ECCs) have a wide range of applications, and compressive strength (CS) is a key aspect of their design, in addition to tensile strength. Supplementary cementitious materials (SCMs) such as fly ash (FL), slag (SL), silica fume (SI), and rice husk ash (RI) play an important role in the development of the CS through the packing effect. The proper use of SCMs to create a sustainable environment is the only option for reducing CO2 emissions from ECC production. The water to binder (or) water to the cementitious material ratio (W/B) is also an important consideration for CS. The ECC CS, which includes SCMs, is reviewed in this paper. The following observations were made as a result of this approach. SCMs have a substantial impact on the ECC CS performance. The CS has an impact on the geometry of the specimen. High W/B causes a significant change in ECC CS.KeywordsEngineered Cementitious Composites (ECC)Compressive strength (CS)Supplementary cementitious materials (SCMs)Sustainable environmentWater to binder ratio (W/B)Geometry
