  • Standard Deviation for Compressive Strength of Concrete

    1. What is Standard Deviation for Compressive Strength of Concrete The standard deviation of concrete is the reliability between the different compressive strength results of a concrete batch. It is also defined as the range of dispersion or variation in the compressive strength result that exists from the mean average or expected value.
