Effect of expansive agent and shrinkage reducing admixture on ECC with polyvinyl alcohol and polypropylene

Abstract

This research aims to determine the strength of engineered cementitious composites. The strength tests like compressive strength, flexural strength, and direct tensile strength were determined. Expansive agent and shrinkage reducing admixture were used. These admixtures used to enhance the strength and reducing the water content in the mix. The expansive agent also increases the compressive strength, but it does not give any changes in direct tensile and flexure properties. Polyvinyl alcohol and polypropylene fibres have excellent structural properties that are ideal for Engineered Cementitious Composites. Superplasticizer increases the workability of the fresh concrete and also it reduces shrinkage. Glass fibre is also used because of its high tensile property. The hybridization with low and high modulus fibres are engaged to increase the strength of Engineered Cementitious Composites.
