Compressive strength - Wikipedia

OverviewIntroductionDeviation of engineering stress from true stressComparison of compressive and tensile strengthsCompressive Strength of ConcreteCompressive strength is often measured on a universal testing machine; these range from very small table-top systems to ones with over 53 MN capacity. Measurements of compressive strength are affected by the specific test method and conditions of measurement. Compressive strengths are usually reported in relationship to a specific technical standard.

How to Evaluate Compressive Strength of Concrete

26/09/2016  It is safe to say that the compressive strength of concrete is the most important parameter used in the design of concrete structures; however, concrete does not provide significant tensile strength. Perhaps, this is the very fundamental idea of building reinforced concrete, where steel reinforcement provide the much needed tensile strength of the section.
