### The procedure for Compressive strength test of Concrete

Compressive strength of concrete Out of many test applied to the concrete this is the utmost important which gives an idea about all the characteristics of concrete.By this single test one judge that whether Concreting has been done properly or not. For cube test two types of specimens either cubes of 15 cm X 15 cm X 15 cm or 10cm X 10 cm x 10 cm depending upon the size of aggregate are used.

A compressive strength of 10 N/mm² at an age of 24 h with a curing temperature of 20°C was targeted to enable demolding. After 28 days an average compressive strength of 38 N/mm² was desired to obtain a concrete strength sufficient for certain applications. The cement-reduced concretes must have sufficient workability.
