Mechanical and durability properties of concrete with granite powder as partial replacement of cement

Abstract

The experimental investigation was performed to evaluate the strength and durability properties of concrete, in which cement was partially replaced with granite powder at 5%, 10%, 15% and 20% by volume. A total of five concrete mix proportions were developed for control and concrete with granite powder. The fresh property test, strength, and durability testes were done for normal strength concrete (NSC) as well as high strength concrete (HSC). The fresh property of concrete was evaluated using slump test, and the strength of concrete was evaluated using compressive strength and splitting tensile strength test. Durability properties were evaluated using water absorption test, sorptivity test, and chloride and sulphate attack test for all concrete mixes. From the investigation, the compressive strength was enhanced up to 10% replacement in NSC and at 5% replacement in HSC. The tensile strength was improved up to 10% replacement in the both types of the concrete. Denser concrete against water absorption was made at 5% & 10% in NSC and 5% in NSC and 10% in HSC concrete. The resistance to chloride and sulphate attack was enhanced at all replacement percentages for NSC as well as HSC.
