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).

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Once cured, the cubes are tested using a compression machine, which ‘crushes’ the cube until it fails giving a compressive strength value. Fresh concrete sampling and testing Different types of concrete testing can be conducted depending on whether the concrete is freshly mixed or hardened.

In some extreme cases, many cubes are taken, and the tests carried out every few days, but as a general rule, the 28-day strength is taken as the target. For some concrete not reaching the desired 28-day strength, the crushed cube remains are submitted for chemical testing to confirm the cement content and water/cement ratio.

Cube Testing. The cubes are generally tested at 7 & 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first.

So, 100mmx100mmx100mm concrete cubes are used in place of 150mmx150mmx150mm cubes to raise the used stress to crush the concrete cubes. For normal concrete strength, the cube size of 150mmx150mmx150mm is already sufficient for the crushing strength of the machine. Cube Test: Instrument And Material.

If the cube has a failed test result at 28 days, then your spares will be used to test on either 42 days or 56 days, depending on what test age you prefer beyond 28 days. Two cubes will be tested (or crush concrete cubes) again with the same cube ID number, but these will be spares. So most probably, a test beyond the 28-day test is likely to pass.
