The following are the major concrete cube test failure reasons, 1) Wrong Mix Poured: The concrete mix prepared is not as per the approved mix design for that particular strength. 2) Wrong Mix Design: There is a mistake in concrete mix design. It is not properly designed and strength is not properly calculated.

Concrete cubes are typically made in moulds with dimensions of 150mm x 100mm x 150mm. The moulds have to meet the British Standard for testing hardened concrete (BS EN 12390-1:2000). When should the cubes be tested? Crush the cubes to test their strength – When each cube is ready for testing, it is put into a concrete crusher. This

Concrete cube test Procedure. Firstly, in a clean and dry pan, fine and coarse aggregates is taken by weight. The quantity of material taken should be enough to prepare at least 3 cubes of 150mm in size. It would be better if well-graded aggregates are used. In general, clean and dry aggregate passing 20mm sieve size is used for coarse
