“Mathematical Model for Compressive Strength Prediction of RAC”

Abstract

This investigates work the compressive strength and predicted compressive strength of concrete specimens cured at the age of 28 days. Natural coarse aggregate (NCA) has been replace with 60 percent, and 100 percent by recycled coarse aggregate (RCA) of construction &demolition (C&D) waste of 30-year-old building and Ordinary Portland Cement (OPC) has been replaced with 20 percent of Ground Granulated Blast Furnace Slag (GGBFS) and 10 percent of Fly Ash(FA). To understand thecompressive strength of concrete of predicted compressive strength was perform and to find suitable results. Develop mathematical model compressive strength and predicted compressive strength of concrete that satisfy. This research presents the outcome of GGBFS and FA as a cement replacement on the physical properties of RCA.
