Abstract :

Water is a critical component in the concrete mix, contributing to its workability and hydration process. Adequate water content is necessary for the proper mixing, placing, and curing of concrete. In areas with lower water availability, managing water in concrete becomes even more crucial, Self-curing concrete is therefore recommended as it reduces the amount of water used during construction process. Concrete is a formulated by mixing cement, fine aggregate, coarse aggregate, and water to produce a cohesive material. The important constituents in concrete is aggregate because it improves the strength and stability of concrete while reducing shrinkage. To conserve aggregate, it is vital to identify substitute aggregate to replace coarse aggregate. Generally, any kind of waste can be used to find alternative materials, which will provide dual advantages. One of the benefits is the use of alternative materials and another is the ability to dispose of trash. The purpose of this research is to analyse the performance of Bethamcherla stone as the partial substitute for coarse aggregate by varying percentages of 10%, 20%, 30%, 40% and 50% incorporating to that poly-vinyl Alcohol by various percentages of 0.03%, 0.06%, 0.12% and 0.24% by weight of cement. The extent of work includes determine Workability of freshly prepared M20 grade concrete by compaction factor and slump cone test and mechanical qualities of concrete including Compressive Strength and Split Tensile Strength for 28 days and 90 days of curing.
