Testing Concrete Cores

As per ASTM:C-42, the preferred length of the capped or ground specimen is between 1.9 and 2.1 times the diameter. If the ratio of the length to the diameter (L/D) of the core exceeds 2.1 reduce the length of the core so that the ratio of the capped or ground.

Comparison of cube strength and cylinder strength

As it appears, there is no linear relationship between the cube strenth and the cylinder strength. However, some times, it can be observed that some designers use 0.8-0.9 factor to get the relevant cylinder strength for a particular cube strength. Now, we need not worry about any factor to calculate the relationship the characteristic stress.

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.
