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 assessed at 3 or 7 days after casting. The preparation, handling, curing and testing of concrete cubes are done according to SANS 5861-3: 2006 Concrete Tests

The concrete minimum compressive strength will be specified by the client/designer in a specific format. An example of this is given below: C40/50. The 40 is the compressive requirement of 40 N/mm² of a crushed 100m concrete core and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete cube.

The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28

Concrete Cube Test Dimensions. In the UK the crushing strength of concrete is measured using compressive strength tests of concrete involve the crushing of 150mm cubes. The correct standard concrete cube size is ensured by using a standard concrete cube mould. In the US and most of Europe the compressive strength of a concrete cylinder is measured.

Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement which hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, such as ciment fondu. However, road surfaces are also a type of concrete, asphalt concrete, where the cement material is bitumen, and polymer

The cubes are then cured in a temperature-controlled water bath for the specified number of days and crushed in a specialised hydraulic press to determine the compressive strength. The cubes are filled in two or three layers with the wet concrete, with each layer being compacted with a standard tamping bar and a minimum specified number of strokes.
