    In general, large specimens have less variability and better representation of the actual strength of the concrete than small specimens. Therefore, the 0.15-m by 0.30-m size is the most suitable specimen size for determining the compressive strength. However, some agencies use 0.10-m diameter by 0.20-m high specimens

    We can find characteristics of concrete with the single compressive strength of the concrete cube test. With this single test, one can find whether concreting is done properly or not. For general construction work, concrete compressive strength varies from 15 Mpa (2200Psi) to 30 Mpa (4400psi) and even higher in commercial and industrial structures. During the production
