Aggregate Crushing Value Test is important to test to be performed on strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm This cylinder is subjected to compressive on the type of parent rock gives the different crushing value of aggregate as a compressive strength
Type 1 failure actually never occurs, the usual shape is type 2 if the cylinder is simply placed into the crushing machine, and there is normal friction between the concrete and the steel plates.

Concrete cubes may get crushed on one side or will develop tensile crack on one or more faces and fail. Fig shown below shows some of the likely unusual failures of concrete cubes. This type of failure will give lower indication of compressive strength of concrete. These are usually due to defects associated with testing machine.

Low operational costs This type of crusher is equipped with a spring release system that protects it against overloads and allows uncrushable materials to pass through the crushing space without damaging the crusher. Inexpensive machine; Disadvantages: The cone crusher cannot take material of all sizes. The materials must be pre-dimensioned for the crusher (usually 200 mm
As per IS Code, the sample selection for the concrete cube test has listed below. The minimum value of Compressive Strength for a cube. As per IS 456, the individual compressive value of a concrete cube should not be less than 75% of its grade. Example – If the concrete grade is M20, then the individual crushing value should not be less than
Answer: Well it's all about the surface area, accuracy in determining the compressive strength and the limit of the compression testing machine to determine the compressive strength of the concrete cubes. Any compression testing machine has a limit of weight that it can exert on the concrete cub
