Test Procedure for Compressive Strength of Concrete 01. The results of compressive strength test of concrete give the idea regarding quality control, acceptance of concrete mix, structures strength estimation, the durability of concrete, healthy life of the structure etc. The compressive strength of concrete ensures that the delivered concrete mix will meet the requirements of the specific strength as designed by the engineer according to the work specifications and requirements. The compressive strength of concrete is the most common performance attribute which is used by the engineer when designing the structures. Such as in freshly mixed concrete, workability test is most important and in the hardened state, destructive tests like compressive strength test- cube test, tensile strength test and non- destructive tests like rebound hammer test, ultrasonic pulse velocity test etc. Hence while working with concrete, there are many factors that are supposed to be checked in fresh condition as well as in the hardened condition. Concrete mix is designed to accommodate a wide range of mechanical and durability properties to encounter the design requirements of a structure. It is a mixture of cement, sand, aggregate, admixtures and water. Concrete is an important material for the construction industry.
