• Compressive Strength of Concrete Cubes - Lab …

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.

14.05.2020· But the British standard mainly uses the cube strength as characteristic strength to represent the concrete in the design formulas. Therefore, knowing the relevant strength classes or the relationship between the structure are important. 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 …

Compressive strength as a concrete property depends on several factors related to the quality of used materials, mix design and quality control during concrete production. Depending on the applied code, the test sample may be cylinder [15 cm x 30 cm is common] or cube [15 cm x 15cm x 15 cm is the most common]. For example, as per ASTM C39, a standard test method is given to get the compressive …
