Compression test on concrete Civil Engineering

Concrete cube testing and maintaining good cube test records does not mean quality control of concrete works. Often the records show excellent cube results but the actual concrete is extremely poor. Concrete cubes are often cast with the stiffer mix (lower water to cement ratio) or using additional cement while actual concreting is done without
