Traditionally, the compressive strength of concrete used to be around 20 to 50 MPa, which is classified as normal strength concrete (NSC). In recent years, concrete with compressive strength in the range of 50 to 120 MPa has become widely available and is referred to as high-strength concrete (HSC). When compressive strength exceeds 120 MPa, it is often referred to as ultrahigh-performance concrete (UHP).

HPC = HSC+ Durability.

Thank you Ms. Doha.

You are welcome dear Dr Munaf.

U follow up.

Thank you Mr. Adel.

In the early 1980 ties High Strength Concrete, Very High Strength Concrete and Ultra High Strength Concrete are used for concretes with a high compressive strength. Later this was replaced with High Performance Concrete and Ultra High Performance Concrete assuming that the performance is more important than the compressive strength of the concrete. However, for both High Performance Concrete and Ultra High Performance Concrete the compressive strength is still used to classify a concrete and not the performance.
