Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc.
The Compressive strength is measured by breaking a cylindrical or cubical concrete specimen of known dimensions in a compression testing machine .The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in MPa (SI) unit however the UTM directly displays the compressive ...

A. According to section 19.2.1.3 of ACI 318-19 the specified compressive strength shall be based on the 28-day test results unless otherwise specified in the construction documents. 3- or 7-day test results are used to monitor early strength gain, especially when high early-strength concrete is used.

This paper covers, briefly, the purpose of compressive strength of concrete test cubes, parameters, which can affect the compression strength of concrete, also some basic and advanced apparatus required for the test and the precautions for the test. It also discusses different types of cube failure that can occur.
The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) in US Customary units or megapascals (MPa) in SI units. Concrete compressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 ...
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. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength ...
Conclusions regarding concrete compressive strength can be derived from a series of tests. The characteristics of concrete strength can be accurately estimated when an adequate number of tests are conducted in accordance with standard practices and test methods. Statistical procedures provide valuable tools when evaluating strength test results.

Compressive strength of concrete cube test is the most important strength test for concrete. This single test gives an idea about all the characteristics of concrete. Concrete are very strong in compression. It is assumed that whole of the compression will be taken up by the concrete at the time designing any RCC structure.
Compression tests (ASTM C 39) are conducted to determine the compressive strength of concrete (or its ability to resist a crushing force). In this test, a standard test load is applied parallel to the longitudinal axis of a pre-molded and properly cured concrete cube of a standard size (BS 1881—125:2013).
