What is the target mean strength?

Target mean strength refers to the desired average compressive strength of concrete or other construction materials, which is typically specified in a project’s design documents. It is essential for ensuring that the material can withstand the loads and stresses it will encounter during its lifespan. The target mean strength is often calculated by considering factors like variability in material properties, safety margins, and the required performance of the structure. It is usually determined through statistical methods based on test results from concrete samples.
