The design of concrete mixes is typically based on the strength requirements of the concrete, which are specified by the grade of concrete. The grade of concrete is denoted by the strength it can achieve after 28 days of curing. Here are the steps to design concrete mixes for different grades of concrete (C10, C15, C20, C25, C30, C35, C40): 1.
