95 Compressive Strength of Concrete

The compressive strength of concrete is very important as it is used more often in compression than in any other way It is rather difficult to give average values of the compressive strength of concrete as it is dependent on so many factors The available aggregates are so varied and the methods of mixing and manipulation so different that tests must be studied before any conclusions can Get price
