Experimental Study on the Compressive Strength of Big

An experimental study of C20, C25, C30, C40, and C50 big mobility concrete cubes that came from laboratory and construction site was completed. Nondestructive testing (NDT) was carried out using impact rebound hammer (IRH) techniques to establish a correlation between the compressive strengths and the rebound number. The local curve for measuring strength of the regression method is set up

2017/7/23GRADE: C25 CONCRETE Strength: 25 Newtons after 28 days. A multi-purpose concrete that is used on a wide range of commercial and domestic construction sites. C25 is often used when pouring foundations (footings). It is also the ideal concrete for domestic

The classification of concrete grades is based on their compressive strength. Each concrete grade e.g. C30/37 is characterized by two equivalent strengths, which in this specific example are 30 MPa and 37 MPa. The first is the characteristic strength f ck of a standard concrete cylinder and the latter is the characteristic strength of a standard concrete cube.

The strength of concrete is divided into twelve grades such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55 and C60. Concrete mix ratios are expressed in two ways: one is expressed in materials used per cubic meter of concrete (Water: Cement: Sand: Gravel), and the other is expressed as a ratio of various materials. for example, C:S:G = 1:2.3:4.2, and W/C = 0.6.
