Construction industry concrete used heavily. The building industry relies heavily on coarse aggregate (C.A.). Due to the lack of C.A., artificial aggregate known as Ferro silica slag (F.S.S.) is the predominant alternative material. The Use of F.S.S. increases concrete strength and lowers construction costs. The strength of concrete is determined by how long it is allowed to cure. Because of improper curing, the hydration of cement problem can be solved by employing a self-curing mechanism. It’s possible to use paraffin wax Light and Heavy in Concrete have a variety of beneficial effects on S.C.C.’s fresh and hardened concrete qualities. The immersing curing agent is a material that retains Water and reduces evaporation; the self-curing admixture incorporates concrete after the standard setting of concrete on account of increased water retention capacity and compares to internally cured concrete. It gives inside assuaging, known explicitly as “self-curing concrete,” in short, less or no external curing is required in another way if outside mitigating may cause better warmth of hydration. Light molecular weight and high molecular weight are two examples of self-curing liquids that can boost the strength and serviceability of concrete. In this investigation, the percentage of paraffin wax in M25 grade concrete was altered from 0%, 0.1%, 0.5%, and 1.0% and compared to internally cured concrete(I). The replacement of coarse aggregate with the optimum amount of F.S.S. Paraffin is then added to concrete in a liquid form, resulting in varied dosages. Based on the literature, the optimum percentage of F.S.S. 40% with paraffin wax light and heavy 1.0% improvement of compression and flexure strength of concrete. Ultrasonic pulse velocity (U.P.V.) and Rapid chloride penetration tests (RCPT) were used to determine dense microstructure and enhanced durability of concrete.
