Modeling and Evaluation of Concrete Tensile Strength Based on Fly Ash Substitution Ratios

Abstract

The tensile strength value is obtained by conducting a compression test by loading the test piece laterally to obtain maximum tensile strength. This study conducted a model to determine the tensile strength value of concrete by evaluating the percentage of fly ash varied by 0%, 40%, and 80%. In the experimental setup, an analytical balance with a cylindrical test specimen measuring 30 cm high and 15 cm in diameter. The test results show that the larger the percentage of fly ash mixture substitution, the smaller the tensile strength value of the concrete produced.
