Compressive Strength Endorsement with Regression Props of Inflection and Tolerance for Material Substituted Self Compacting Concrete with Fiber Reinforcement

Abstract

This research comprises Self-Compacting Concrete (SCC) and Polypropylene fibers to enhance its mechanical properties, tensile strength and crack resistance. Self-Compacting Concrete (SCC) has gained significant attention in the construction industry due to its ability to flow and fill intricate forms without the need for external compaction. The use of different materials as substitutes in SCC with Polypropylene fiber reinforcement poses challenges in determining the compressive strength, as the properties of the substituted materials can vary significantly. This study focuses on developing a comprehensive approach for endorsing the compressive strength of fiber-reinforced SCC with material substitution. Regression analysis techniques are engaged to establish a mathematical model that correlates the compressive strength with key influencing factors. The study identifies two critical properties: inflection and tolerance, which significantly affect the compressive strength of the substituted SCC. This study determined through considering different combinations of substitution materials and their respective proportions. It takes into account the potential variations in the physical and chemical characteristics of substitute materials. The optimum limit is defined, which indicates the maximum allowable deviation without compromising the compressive strength. The developed model is validated through an extensive experimental test, involving a range of substitution materials, fiber types and proportions. The results demonstrate the accuracy and effectiveness of the proposed approach in predicting the compressive strength of fiber-reinforced SCC with fly ash substitution. This study gives the advancement of SCC technology by providing a comprehensive framework for validating the compressive strength of fiber-reinforced SCC with material substitution.
