Different Types of Concrete Includes Strengths amp Grading

Concrete strength is measured by the weight it can withstand 28 days after it has been laid and cured. Our concrete strengths range from grade C10 to C40. C10, with a strength of 8 newtons, is designed for kerb backing and bedding. C40, our strongest concrete with a strength of 40 newtons, is designed to withstand heavy-duty loads.

HighStrength Concrete Portland Cement Association

HighStrength Concrete Portland Cement Association

High-Strength Concrete. In the early 1970s, experts predicted that the practical limit of ready-mixed concrete would be unlikely to exceed a compressive strength greater than 11,000 pounds square inch psi. Over the past two decades, the development of high-strength concrete has enabled builders to easily meet and surpass this estimate.
