Why Concrete Has Good Compressive Strength But Bad
2021-11-12 Concrete has tremendous compressive strength, so to make it sturdier, engineers add steel bars inside concrete structures. This adds to the tensile strength of the concrete structure to make it a strapping, robust building. Notice the steel rods. They impart tensile strength to the concrete structure.

Testing the Compressive Strength of Concrete — What,
2021-11-16 The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) in US Customary units or megapascals (MPa) in SI units. Concrete

Research progress on the dynamic compressive properties
2021-11-1 Before micro-cracks propagate into macro-cracks, more new micro-cracks have been nucleated and enlarged, consuming more energy and leading to higher compressive strength. Li and Meng [ 25 ] observed that the lateral confinement in the SHPB test was an important factor causing the dynamic strength enhancement of concrete.
