Strength of Cement - Building Research Institute (P) Ltd.

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 28-days compressive strength of the cement -mortar cubes prepared out of that cement in a standard manner will be of 53 MPa.

3. Properties of Concrete - The University of Memphis

Concrete has almost no tensile strength (usually measured to be about 10 to 15% of its compressive strength), and for this reason it is almost never used without some form of reinforcing. Its compressive strength depends upon many factors, including the quality and proportions of the ingredients and the curing environment.
