Mathematical Expressions Model to forecast for Chloride Ion Penetration and Comp. Strength of Recycled Coarse Aggregate Concrete Incorporating Meta-kaolin

Source abstract

Abstract This research investigates the mathematical modeling of compressive strength (CS) of concrete cured cube at 3, 7 & 28 days and chloride penetration resistance of cylindrical concrete specimens cured at 28 days incorporating of Meta-kaolin (MK). The experimental data results were shown various concrete specimens close to recognize compressive strength (CS) and penetration of chloride ion. Ordinary Portland cement (OPC) has been partial replacement of 0%, 5%, 8%, 12%, 16%, 18% and 20% by Meta-kaolin (MK). Compressive strength (CS) results discover through the cubes and rapid chloride penetration test (RCPT) presented. Two predictive regression models established, first for compressive strength (CS) of concrete specimen at the days of 3, 7, and 28 and second for charge passed Q at 28 days. To predictive the mathematical models have been established and have good precision, correlation by experimental results of data.
