Abstract

In order to study the optimal combination of mechanical properties of modified concrete under multiple indicators, the orthogonal test results of rubber particle basalt fiber fly ash modified concrete were analyzed using queuing scoring method and matrix analysis method, with rubber particle substitution rate, basalt fiber content, and fly ash content as factors, compressive strength, splitting tensile strength, flexural strength, tension-compression ratio, and bending-compression ratio as indicators. The results indicate that the order of influence of various factors on the mechanical properties of modified concrete is rubber particle substitution rate, basalt fiber content, and fly ash content. The optimal combination of mechanical properties of modified concrete based on the queuing scoring method is A1B2C1, with a rubber particle replacement rate of 5%, a basalt fiber content of 4%, and a fly ash content of 10%. The optimal combination of mechanical properties of modified concrete based on matrix analysis method is A1B3C1, with a rubber particle substitution rate of 5%, a basalt fiber content of 6%, and a fly ash content of 10%.
