%X Optimization using the response surface methodology (RSM) for the modulus of elasticity utilizing crumb rubber in partial replacement with the sand along with the incorporation of hybrid fibers such as PVA and tirewire in engineered cementitious composites (ECC). The crumb rubber in ECC ensured the homogeneous dispersion of fibers and also restricted the fracture toughness of the matrix. An appropriate hybrid combination of fibers facilitated in balancing the ultimate strength, strain capacity and crack width with the proper volume of PVA and tirewire fibre. The modulus of elasticity for hybrid combination was more than the ECC with only PVA fibers and in meanwhile the tirewire fibers balanced the negative effect due to the crumb rubber and PVA fibers on modulus of elasticity. RSM aided in optimizing the ingredients in the ECC to achieve better performance of the ECC material. RSM optimized results using ANOVA (Analysis of variance) was experimentally verified and it was found that less than 5 of the difference in the results with the desirability of 1. © IAEME Publication.
