Compressive strength of concrete cube test provides an idea about all the characteristics of concrete.By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

Note : Under control conditions if Target average compressive strength is achieved then at field the probability of getting compressive strength of 30 MPa is very high ...

2.4 Hardened concrete 2.4.1 Compressive strength Compressive strength tests were conducted on cured cube specimen at 7, 28 and 56 days age using a compression testing machine of 200 tons capacity. The cubes were fitted at centre in compression testing machine and a very small load was applied to keep the cube in position.

Compressive Strength. The compressive strength of any material is defined as the resistance to failure under the action of compressive forces. Especially for concrete, compressive strength is an important parameter to determine the performance of the material during service conditions.

compressive and split tensile strength of chopped basalt fiber reinforced concrete of M20 grade concrete.

M20 grade of concrete with 0.20%, 0.25%, 0.40%, & 0.45%, proportions of glass fibers and 0.30%, 0.35%, 0.50%, &0.55% proportions of steel fibers have been added with concrete. Variations in flexural, spilt tensile and compressive strength of concrete have been compared with M20 grade of concrete.

Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.

Concrete grades are denoted by M10, M20, M30, according to their compressive strength. The "M" denotes Mix design of concrete followed by the compressive strength number in N/mm2, "Mix" is the respective ingredient proportions which are Cement: Sand: Aggregate Or Cement: Fine Aggregate: Coarse Aggregate.
