2020-5-29Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce sie as opposed to which withstands loads tending to elongate. In other words compressive strength resists being pushed together whereas tensile strength resists tension being pulled apart.
Fire response of concrete structural members is dependent on the thermal mechanical and deformation properties of concrete. These properties vary significantly with temperature and also depend on the composition and characteristics of concrete batch mix as well as heating rate and other environmental conditions.
