Experimental studies on mechanical and durability properties of high performance concrete with partial replacement of fine aggregate with crushed Quartzite and binding material by fly ash and silica fume

Abstract

The high performances concrete’s demand growing day by day due to its mechanical properties like compressive strength and it’s durability characteristics therefore the Research on high performance concrete on its verge. The availability of natural fine aggregates are diminishing day by day there by it is the time to search for alternative. Many researches are using utilizing industrial waste in High performance Concrete. In the present study, M60 grade of the concrete was used and designed as per the mix design standards of American Concrete Institute (ACI, 234R-96). The mechanical properties of HPC, such as compressive strength, split tensile strength, and modulus of elasticity, as well as durability properties, such as acid resistance test, sulphate resistance test, chloride resistance test, ultrasonic pulse velocity test, and alternate wet and dry test, were determined using specimens of regular concrete mix and modified Crushed Quartzite concrete mixes. According to the experimental findings, HPC has good mechanical and durability features when 30% crushed quartzite is substituted for fine aggregate, and the amount of binder is determined by the compressive strength of concrete when varied amounts of fly ash and silica fume are used. Optimization of admixture arrived as Fly ash 15% and silica fume 10% to the weight of cement content.
