Procedure for Concrete Compression Test Concrete Sample

Cube test REPORT - DCC2042

Whereas for hardened concrete, they are cube compression test and flexibility compression beam test. Hardened concrete test is usually carried out when concrete is at age 3, 7, 14, 21, and 28. Concrete strength increases according to its age. In general, concrete would have acquired 70 % strength on the 7th day. 4.
