Compressive Strength Test of Concrete - Detailed …
As per IS 456, the individual compressive value of a concrete cube should not be less than 75% from its grade. Example - If the concrete grade is M20, then the individual crushing value should not be less than 15 N/Sqmm. The individual crushing value difference between the cube should not be greater than 15%.
Compressive Strength of Concrete -Cube Test, …
The compressive strength of the 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.

Concrete strength is measured by the weight in can withstand 28 days after it has been laid and cured. Our concrete strengths range from grade C10 to C40. C10, with a strength of 8 newtons, is designed for kerb backing and bedding. C40, our strongest concrete with a strength of 40 newtons, is designed to withstand heavy duty loads.
Compressive Strength of Concrete | Cube Test, …
As we all know that concrete is a mixture of sand, cement, and aggregate. The strength of the concrete depends upon many factors like individual compressive strength of its constituents (Cement, Sand, aggregate), quality of materials used, air entrainment mix proportions, water-cement ratio, curing methods and temperature effects.
Strength of Concrete vs Grades of Cement
Cements of different grades viz. 43 OPC (IS–8112) 1, 53 OPC (IS-12269) 2 and Portland Pozzolana cement (fly ash based), IS-1489 Part I 3 etc. with different brand names are available in the market. However, when tested in the laboratory these cements do not give the strength corresponding to their grades in case of OPCs and markings such as 43 MPa 53 MPa on their bags in case of Portland ...
