Question: Can you provide mix proportions for a C32/40 concrete?

To achieve a true characteristic strength, assessment of the mix design must be carried out pre-contract. If a large quantity (several cubic metres or more) of concrete of specified characteristic strength is required, then it is suggested that ready-mixed concrete is used.

Different Grades of Concrete, Their Strength and Selection

What is Grade of Concrete? Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.

concrete divided by the weight of cement in the concrete. The water to cementitious ratio, W/Cm, is the weight of mix water in the concrete divided by the weight of the cementitious material, where the cementitious material is a combination of cement and pozzolans. The ratio is expressed as a decimal (example 0.446).
