Crushing Concrete Cube or Cylinder at 28 days
The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason for this is to verify the strength given in the design mix. Let’s look at an example of a concrete column. Commonly, it has 60 megapascals of specified strength. When you crush it, the result should be equal to or more than 60 Mpa.

What is the crushing strength of M50 grade concrete?
Answer: Crushing strength is another term for compressive strength. M50 denotes concrete mix with a characteristic cube compressive strength (denoted by fck) of 50 N/square mm or 50 MPa.

The effect of temperature on the compressive strength of concrete
The crushing strength of concrete at temperatures up to 600°C was independent of the water/cement ratio used but was influenced by the aggregate/cement ratio. Concrete specimens loaded to produce normal design compressive stress during the period of heating showed less reduction in strength than specimens without imposed load.

Compressive Strength of Concrete Cylinders
The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by applying continuous load over the cylinder until failure occurs. The test is conducted on a compression-testing machine.

Concrete Under Multiaxial Loads
Concrete very rarely undergoes a crushing or compression failure. 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. Let us consider various cases of loading concrete (in all the cases, the effects of friction at the ends is neglected), as shown in Figure 1.
