Contrary to tensile strength which resists tensile force or elongation of a body, compressive strength resists compressive force or compression of a material which tends to shortens it. The ultimate compressive strength of a material is defined as the point where the uniaxial compressive stress reaches its maximum value, i.e. element fails.
Dec 01, 2010· Normally, the elastic modulus of concrete relates to its compressive strength as the simple equation (3), (3) E = σ ε where E is the modulus of elasticity (MPa), σ is the compressive stress (MPa), and ε is the strain value (dimensionless). Naturally, strain along the time of concrete-like materials would slightly decrease after hardened.
Jan 01, 2021· The compressive strength of concrete ranges from 15 MPa (2200 psi) to 30 MPa (4400 psi) for residential concrete and is high in commercial structures.

Type A soils with an unconfined compressive strength of 1.5 tsf can be readily indented by the thumb; however, they can be penetrated by the thumb only with very great effort. Type C soils with an unconfined compressive strength of 0.5 tsf can be easily penetrated several inches by the thumb, and can be molded by light finger pressure.
Compressive strength vs tensile strength | Stress & Strain.
