In the concrete mix PVA (polyvinyl alcohol) fibre can be used as cement replacement. Enhancement of the compressive as well as tensile strength of concrete with retrofitting method using the SHCC (strain hardening cement based composite) is used in this paper. Polyvinyl alcohol fibre concrete is an ideal material for achieving goals like controlling thermal cracking, plastic shrinkage, durability, toughness and abrasion resistance. There are two critical issues with this type of cement replacement i.e. the changes in physical properties of concrete with respect to compressive, tensile strength and cost analysis of alternatives. The result from this research shows a linear diminution in strength with linear increase in the relative % age of PVA fibre to cement. Experiments were performed on concrete mixtures with varying PVA fibre contents i.e. 0%, 1%, 2%, 3%, 6% and 9%. The optimum level of PVA fibre was determined as 1% based on the compressive strength and tensile strength. For SHCC the cubes specimens for compressive strength of size (150mm×150mm×150mm) with mild steel rods were used to early setting and hardening and in tensile strength the dumble shape moulds were used. The compressive strength at 3days, 7days and 28days has been checked after the curing of sample and tensile strength is checked at 28 days.
