Concrete Cube Testing. Concrete cube testing is a reliable means of testing the compressive strength of concrete to ensure that it will meet the necessary standards for the project for which it is being used. Cube testing involves taking a sample of freshly mixed concrete and pouring it into cube-shaped moulds.
The strength of concrete is generally measured by testing concrete cubes which are prepared from the concrete used in that particular construction. The cube strength of concrete is specifi ed by a structural engineer and is assessed by crushing concrete cubes at a specifi ed age (28 days after casting). Early strength may also be
Concept and significance of the Aggregate crushing value test. The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the …
Due to non-uniformity in the materials and less voids detection at rebound hammer, the crushing cube test showed 16.6% more compressive strength than the hammer test in varied curing and 20% in MBC. As the hammer test is a non-destructive testing, the compressive strength is at reserve side compared to crushing strength.

What is a concrete cube test? A concrete cube test is a way to test the strength of concrete. The concrete is cast into cube moulds and allowed to cure. It is then crushed at intervals of 7 or 28 days. This test is used to determine whether concrete that has been poured at a construction site has the specified compressive strength.
