Anti-seepage anticorrosive concrete material and preparation method thereof
The invention discloses an anti-seepage anticorrosive concrete material and a preparation method thereof. The concrete material consists of the following components in parts by weight: 100-200 parts of portland cement, 30-150 parts of crushed stones, 40-120 parts of fine sand, 10-50 parts of calcium chloride, 8-20 parts of magnesium silicate, 5-16 parts of active calcium silicate, 3-10 parts of sorbose calcium, 3-12 parts of dialuminium hydrogen phosphate, 5-13 parts of strontium oxide, 4-15 parts of brucite powder, 15-35 parts of fly ash, 3-8 parts of white mud powder, 6-18 parts of silica micro powder, 2-10 parts of polyvinyl alcohol, 15-35 parts of phosphorus gypsum, 2-6 parts of 12-hydroxyl lithium stearate, 1-8 parts of potassium tripolyphosphate, 4-9 parts of sodium allylsulfonate, 0.1-4 parts of a water reducing agent, 0.1-3 parts of a swelling agent and an appropriate amount of water. The preparation method of the concrete material is an injection molding method. The anti-seepage level of the concrete material prepared by the method disclosed by the invention is greater than P12 level, the corrosion coefficient is 0.84-0.92, and the anti-seepage level and the corrosion coefficient are higher than those of ordinary concrete; and moreover, the 28-day compression strength of the concrete material is greater than 51.8MPa, which shows that the concrete material prepared by the method disclosed by the invention keeps good compression strength, and the seepage resistance and the corrosion resistance are relatively improved at the same time.
