The invention discloses crack-proof concrete. The crack-proof concrete is characterized by comprising, by weight, 300-500 parts of cement, 100-200 parts of medium sand, 200-400 parts of fine aggregate sand, 200-400 parts of coarse aggregate stones, 4-8 parts of admixture and 160-200 parts of water. By means of the modes that the content range of each component is determined, a better synergistic effect of each component is guaranteed, and particularly aiming at the selection of the admixture is conducted, the performance such as water seepage prevention, impact resistance, abrasion resistance, water reduction, frost resistance and crack resistance is obtained by the concrete, and the crack-proof concrete has the advantages of being good in crack resistance, impact resistance, water proofness, slump, construction performance and the like.
