Mar 09, 2020·Compressive strengthis the capacity of material or structure to resist or withstand undercompression. TheCompressive strengthof a material is determined by the ability of the material to resist failure in the form of cracks and fissure. In thistest, the impact force applied on both faces of Mortar specimen made withCementand the maximumcompressionthatcementspecimen bears without failure recorded. In Technical termscompressive strength of cement…
