For normal concrete and HSC, the concrete compressive strength test results from cube specimens are generally higher than cylinders specimens [6]. As states in BS 1881, the compressive strength of concrete gained by cylinder specimens is equal to 0.8 times of the compressive strength gained by cube specimens.

The compressive strength of concrete (fc'') is a nominal material value. If you were to actually break 100 cylinders of same strength concrete though, you would get a decent amount of variability. This variability comes from different aggregate size, different w/c ratios, and other parameters.

The characteristic strength of concrete is the result of the compressive strength of the concrete cube test. The design strength is the required strength of concrete to be designed as per the IS code. For example, assume that the strength of concrete required M25, and the target design strength is 28.5 N/Sqmm.

Concrete Cube Compressive Strength . The Concrete cube test provides details about all the characteristics strengths of concrete.From the result of this cube test, we can judge whether Concreting has been done properly or not.. The strength of concrete for general construction varies according to the grade of concrete from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and

The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28

Plain concrete (Fig. 2.2) has compressive strength—the ability to resist crushing loads; however, its tensile strength is only about 10% of its compressive strength. Its tensile strength is so low that it is nearly disregarded in design of most concrete structures. Reinforced concrete is a combination of adequate

Typically, tensile strains generated in the lateral direction (perpendicular to the loading direction) due to Poisson effect are responsible for cracking leading to failure of concrete.
