Concrete strength in compression is the common characteristic used in the design of concrete structures. However, in general, there are two different types of concrete specimens specified for the determination of concrete strength in compression. They are the standard 150mm diameter by 300mm length cylinders and the standard 150mm cubes.
cube size is 150x150x150, because it has been set as standard size, the value of compressive strength of which has been standardized at 28 days.We can also use 200mm cube, but you have to convert the compressive strength of 200mm cube to the equivalent of 150mm cube to know the actual strength of …

The ability of hardened concrete cube to resist the compression loads applied on the surface is known as . the compressive strength of ... Why was the size of mould chosen ...
The concrete satisfies the compressive strength requirements if it complies to paragraph 8.2.1. and appendix A and B of MSZ 4798-1:2004 Hungarian standard regarding the compressive strength and the body density. During compressive strength testing and evaluation of the test result …
7-day compressive strength test results are often used to monitor the gain of early strength and they are estimated to be about 64% to 70% of the 28-day strength. As such, it serves as a warning signal to both concrete producers and contractors should the 7-day compressive strength test results are far less than 75% of the 28-day strength.

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength, compressive ...
