1.1 Introduction In modern days, concrete is one of the most commonly used materials for construction, such that it have a low cost but high compressive strength. Concrete is a mixture of cement, aggregate and water. Concrete can be divided into different types at which different type of concrete have specified properties for specific usage. After curing, hardening of concrete is undergone which the mechanical properties of the concrete would change with time. It is due the hydration in the wa...
