· And the main equipment used for crushing concrete can be divided into two types: traditional fixed crusher and mobile concrete crusher, among which small crushing equipment is favored by users. Small jaw crusher the best choice for users. Although the compressive strength and hardness of concrete are not high, due to the porosity and the formation type, .

· Compressive strength as per American Codes. In case of American codes, compression strength is defined in terms of cylinder strength fc'. Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression loading.

M20 is also a common type of grade concrete. M20 has a compressive strength that gets added up to 28 days. PROPERTIES OF THE M20 GRADE CONCRETE: The M20 Grade Concrete comes in a mix ratio of 1:: sand and three aggregate. TheM20 stands for the mixture of aggregate, sand, and cement prepared so as the whole cement concrete cube of size becomes 154 cm by 15cm .

Understanding Concrete Grades . Based on their strength, Concrete is classified into different grades like M5,, M10, M15, M20 etc. The letter "M" stands for "Mix" and the following number denotes the characteristic compressive strength of concrete in 28 days of curing.

The reason being: With constant research and development in the field of cement technology and its manufacturing process,a M20 mix of "1::3″(by volume) would be too rich, over engineered and uneconomical (~ bags of cement per cum) and will ultimately result into a M30 concrete and above (IS:456 too have the minimum cement/cementitious content of 06 bags for M20). .

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 ...
