Study on impact of fiber hybridization in material properties of engineered cementitious composites

Engineered Cementitious Composite (ECC) is a type of improved high-performance fiber reinforced cementitiouscomposites with good tensile, compression and flexural behavior. ECC is known for their strainhardeningbehavior under tension and has been increasingly applied in engineering practice. The process ofadding two or more fibers in a mix is known as hybridization. The hybrid composite drives benefits fromeach of the individual fibers added and exhibits improved ultimate strength and strain capacity compared tothe mono-fiber composites. The major applications of ECC are structural reinforcement in the constructionand also organic fiber hybridization is valid only for underwater conditions and they will provide additionaltests concerning burnability or flammability. This work presents the results obtained from three ECC mixes(PVA, PP, STEEL) and four Hybrid Engineered Cementitious Composites (HECC) with differentcombinations of volume fraction with PVA, PP, STEEL. The experimental studies have been carried out toinvestigate the mechanical behaviors of ECC and HECC. The results indicate that this hybridation processhas a notable achievement in compressive strength, direct tensile strength and flexural strength.Keywords: Engineered Cementitious Composite, Compressive Strength, Flexural Strength, Direct TensileStrength, Composites with Organic Burnable Material
