The invention relates to high anti-cracking large volume radiation-proof concrete. The concrete is characterized by comprising water, gelled material, fine aggregate, coarse aggregate, water reducing agent and fibers, wherein the gelled material consists of cement and mineral admixture, and the fibers consist of steel fibers and lead borate polyethylene fibers; and the components have the following proportion: 150 to 170 kg/m<3> of water, 250 to 450 kg/m<3> of cement, 100 to 300 kg/m<3> of mineral admixture, 1,000 to 1,800 kg/m<3> of fine aggregate, 1,500 to 2,200 kg/m<3> of coarse aggregate,water reducing agent in an amount which is 0.6 to 1.2 percent of the total mass of the gelled material, steel fibers in an amount which is 0.5 to 1.5 percent of the total volume of the gelled material, and lead borate polyethylene fibers in an amount which is 0.8 to 1.2 percent of the total volume of the gelled material. The concrete has good physical property and good cracking resistance, and further enhances the radiation resistance.
