Abstract

Concrete is a versatile material of construction used globally. River sand and cement are essential materials in concrete. River sand being used as fine aggregate constantly in concrete leads to its depletion which causes strain in environment simultaneously affecting the sustainability in construction. This problem could be solved by replacing the river sand with industrial waste such as granite powder. With the objective of developing concrete for sustainable concrete, it was therefore decided to Sand replaced with granite powder at the rate of 0%, 25%, 50%, 75% and 100%, and silica fume replaced by cement at 7.5%, Fly Ash at 10%, and slag at 10%. To reduce consumption of water, superplasticizer was used at a dosage of 1%. In this research to evaluate the resistances of this concrete to chemical attack such as acid, chloride and sulphate attack for M60 grade of concrete.
