Prism compressive strength f cp The compressive strength of 150×150×300mm prism, cured in standard condition, 28 days. The relation of prism compressive strength and compressive strength is f cp =0.7 ～ 0.8f cu §4.4.5 Other strength

Tensile strength is tested through split tensile testTensile strength is tested through split tensile test Split tensile test strength experiment is shown in the videoSplit tensile test strength experiment is shown in the video Tensile strength

PrinciplePrinciple –Fig is the ketch map of split tensile test. – Apply linear load distributed evenly on two opposite surface, thus the tension stress will be produced on the vertical surface affected by the external force. –This force will be calculated by the elastic theory. Fig Sketch Map of Split Tensile Test
