The invention relates to environment-protection energy-saving concrete antifreeze, which is made by mixing the following materials according to the share ratio of quality; rubber powder of 100 parts,water reducing agent of 2 to 10 parts, magnesia of 10 to 40 parts, alum calcimine of 10 to 40 parts and anhydrite of 5 to 30 parts. The invention makes full use of the solid waste of rubber powder, thereby having the advantages of environmental protection and energy saving. Besides, the volume of the rubber powder cannot be changed in the process of mixing, transportation and pouring, thereby overcoming the influence to the performance of concrete due to the damage of the air content of air entraining agent. The freeze resisting property of the concrete can be greatly improved by mixing the invention to the concrete according to 10 to 25 percent of the weight of the cement.
