Abstract This paper is focused on the study of Hybrid Engineered Cementitious Composite (HECC), a unique member of High Performance Fiber Reinforced Cementitious Composite (HPFRCC) which is blended with steel and polypropylene fibers making it as a hybrid cementitious composite. The combination of the steel and polypropylene fibers benefits the properties of the individual fiber and exhibits the synergistic response. The mortar based HECC as well as conventional concrete were tested for mechanical properties to know the strength and to understand the stress-strain relationship. The results shows that based on the hybridization, incorporating steel and polypropylene fibers improved the mechanical properties (compressive strength, splitting tensile strength and flexural strength) of HECC by bridging and minimizing the crack width thereby increasing the ultimate load. The stress strain relationship of HECC resulted in the higher value of modulus of elasticity compared to conventional concrete.
