Abstract

The invention provides an anti-cracking impermeable concrete and a preparation method thereof. The anti-cracking impermeable concrete comprises following raw materials, by weight, 160 to 200 parts of cement, 15 to 20 parts of nickel slag micro powder, 10 to 12 parts of ultra-fine fly ash, 40 to 50 parts of sand, 8 to 14 parts of spathic iron, 2 to 4 parts of diatom mud, 4 to 5 parts of sodium sulfate, 2 to 4 parts of potassium chloride, 12 to 16 parts of calcium carbonate, 8 to 15 parts of blast furnace slag, 2 to 4 parts of aluminium hydroxide, 6 to 10 parts of dicalcium silicate, 5 to 8 parts of phenolic resin, 2 to 5 parts of dipropyl ethanediol, and 1 to 3 parts of potassium stearate. The anti-cracking impermeable concrete is capable of preventing generation of surface and internal cracks caused by non-structural reasons such as concrete temperature and drying shrinkage effectively, and possesses excellent impact resistance, impermeability, corrosion resistance, and rust resistance.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to an anti-crack and anti-seepage concrete and a preparation method thereof. Background technique [0002] Concrete is an essential and important material in building construction, but because concrete is a brittle material, it is easy to produce cracks, especially in the construction of tunnels and bridges. Therefore, higher requirements are put forward for the impermeability, crack resistance and long-term life of concrete, and the development of a concrete with high working strength, waterproof and crack resistance has become an urgent problem to be solved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides an anti-crack and anti-seepage concrete and a preparation method thereof. [0004] Scheme of the present invention is achieved by: [0005] An anti-crack and impervious concrete, comprising the following raw materials in...
