An improved concrete expansive agent comprises the following raw materials in parts by weight: 7-10 parts of polyvinylsilicone oil, 6-9 parts of calcium mahogany sulfonate, 5-9 parts of borax, 6-8 parts of alkali lignin, 7-11 parts of hydrocarbon resin, 5-10 parts of isopropyl alcohol, 6-11 parts of melamine, 3-8 parts of nitrite, 6-11 parts of calcium chloride, 4-9 parts of urea, 4-9 parts of calcium of molasses, 6-11 parts of quicklime, 5-9 parts of aluminium dihydric phosphate and 8-13 parts of aluminium sulphate. The improved concrete expansive agent has the benefits that the crack resistance of concrete is improved, and meanwhile, the concrete expansive agent has excellent tolerance, and can improve the waterproofness of concrete.
