An improved anti-crack concrete is prepared from the following raw materials in parts by weight: 6 to 8 parts of zinc stearate, 7 to 11 parts of fatty alcohol-polyoxyethylene ether, 3 to 9 parts of bentonite, 80 to 140 parts of cement, 15 to 30 parts of PC, 2 to 8 parts of borax, 4 to 11 parts of sodium silicate, 5 to 7 parts of carbon powder, 5 to 10 parts of barium sulfate, 2 to 6 parts of quick lime, 0.5 to 2 parts of cellulosic fibers, 90 to 200 parts of gravel, 2 to 5 parts of lauryl sodium sulfate, 4 to 8 parts of a water reducing agent, 5 to 7 parts of silica fume and 6 to 12 parts of anhydrous calcium sulphoaluminate. The invention has the beneficial effects that the improved anti-crack concrete has excellent waterproof ability and anti-cracking ability, and meanwhile is good in caking property and less in distortion; excellent heat preservation and anti-permeability effects are realized.
