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

What Are the Different Grades of Concrete? Concrete grades are determined by concrete's compressive strength 28 days after it has been poured. The strength is measured in psi, or pounds per square inch. The greater the psi rating on a mix of concrete, the stronger the concrete will be after it has been poured and set. The required strength of
