The influences of granite particle as a mixing material of high-strength concrete

Abstract

The aim of this study is to investigate the effect of granite particle on the properties of high strength concrete by the partial substitution as fine aggregate. By grouping two categories as concrete with and without admixture is also performed in this experiment. The granite particle substitution percentage for concrete with admixture is set with 0%, 20%, 30%, 40% and 50% by weight of fine aggregate and 0%, 10%, 15% and 20% by weight of fine aggregate for concrete without admixture. The testing of concrete strength is conducted with compressive, split tensile, flexural, water permeability, and microstructure. The result shows that the content of granite particle in concrete affects negatively on the properties of concrete without the help of admixture, but except the flexural strength. For the concrete with the combination of superplasticizer, the substitution of granite particle as a fine aggregate can be performed up to 50% without affecting the compressive strength and flexural strength of concrete.
