The Experimental Investigation of Durability Test on Concrete Cubes

Abstract

 Concrete is considered to be the most widely used and versatile material of construction all over the world.
Durability and strength are two most important criteria for the design of reinforced concrete structures. These are the
two requirements for the long term performance of concrete structures. In chemical industry, concrete is affected by
different chemical like chloride, sulphate, carbonation of concrete etc. In this work, the characteristic strength for M30
grade of concrete and for micro concrete is checked. The cubes after 28 days of curing in water is immersed in 5%
H2SO4 and 5% HCL of the total volume of water; separately for 28 and 56 days to evaluate the decrement in the strength
as compared to normal condition.
