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
Fill the cone with the concrete sample in three stages. Once each stage is filled, tamp the mix with the tamping rod 25 times. After the third tamping the excess concrete shall be struck off flush to the top of the cone. Lift the mould carefully upwards, to minimise disturbance of the concrete inside. The concrete will slump.

The Cube Test Controller enables the fully automatic control of a hydraulic press for the testing of concrete cubes. Cube Press is designed to conduct compression and crushing strength tests (ACV) on Concrete cubes. Compact four column high stiffness welded frame or welded steel load frame with a high degree of mechanical stability.
The compressive strength of M20 grade concrete varies between 17 and 23 N/mm2 (i.e. between 170 kg/cm^2 and 230 kg/cm^2) after 28 days curing. This means that the concrete can withstand a compressive load of 170 to 230 kg/cm² before it fails.. In compressive strength test of concrete cube the push force applied on the both faces of concrete …

Concrete Testing Equipment (e.g. Cube crushing machines) Concrete is one of the most used materials in the construction industry. Several variables contribute to define the quality of the concrete utilized for a structure
The aggregate crushing value formula is given below, Aggregate crushing value = (W3 / W) or W3 / (W2 – W1) W1 = Empty weight of cylindrical Measure. W2 = Weight of Aggregate with Cylindrical Measure. W = W2 –W1 = Weight of Aggregate Sample. W3 = Weight of crushed aggregate sample passed through 2.36 mm IS Sieve.
