The invention discloses anti-cracking self-waterproof concrete. The concrete is prepared from the following formula: 390-410 kg/m<3> of a cementing material with water-cement ratio being 0.38-0.40 andwater consumption being 150-160 kg/m<3>, 3-6 kg/m<3> of an admixture, 705-735 kg/m<3> of fine aggregates and 1066-1075 kg/m<3> of coarse aggregates; and the cementing material comprises cement, fly ash and slag powder, and the proportion of the cement in the cementing material is greater than or equal to 50%. According to the concrete disclosed by the invention, high durability of low heat and low shrinkage is realized through reasonable matching of various components, the concrete is prepared and applied to steel shell immersed tube engineering, the strict requirements on impermeability andcrack resistance can be met, and finally, the concrete material which is compact, low in permeability, few in macroscopic defects, stable in volume and low in dispersion degree is formed.
