Strength of Cement
Strength of cement is the most important of all the cement properties. Grades mentioned in the cement bags as 53/43 grade OPC/PPC in fact represent the strength of the cement. 53 Grade OPC Cement simply means that 28days compressive strength of the cementmortar cubes prepared out of that cement in a standard manner will be of 53 MPa.

HighStrength Concrete
HighStrength Concrete. In the early 1970s, experts predicted that the practical limit of readymixed 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 highstrength concrete has enabled builders to easily meet and surpass this estimate.

What Is Meant By "Compressive Strength of Concrete"?
08/02/2021 · CS = F ÷ A, where CS is the compressive strength, F is the force or load at the point of failure and A is the initial crosssectional surface area. Compressive strength is measured in psi (pounds per square inch). The higher the psi the stronger, and consequently more expensive the concrete is. The minimum psi required depends on the project ...
