Prediction of flexural strength by using RSM

Abstract

In this study, a statistical method was applied to analyze the experimental data of the compressive strengths, flexural strengths and elastic moduli of cementitious materials. For this purpose, response surface methodology (RSM) was adopted in optimising experimental data obtained in previous study. Regression equation was yielded by the application of RSM relating response variables to input parameters. With the help of this method, the experimental results could be predicted accurately within an acceptable range of experimental errors. Also, a new empirical relationship between flexural strength, modulus of elasticity and compressive strength is proposed.
