Water-repellent aerated concrete block and preparation method and application of water-repellent aerated concrete block
The invention discloses a water-repellent aerated concrete block and a preparation method and application of the water-repellent aerated concrete block. The preparation method comprises the steps of mixing cement, coal ash, water and aluminum powder so as to obtain a mixture M1; adding lime, a waterproof agent, a foam stabilizer and water-absorbent resin into the mixture M1 so as to obtain a mixture M2; pouring the mixture M2 and putting the mixture M2 into a mold for primary maintenance; demolding the mixture M2 after primary maintenance and cutting so as to obtain a block prototype; carrying out steaming and pressing maintenance on the obtained block prototype so as to obtain an aerated concrete block. Corresponding to 100 parts by weight of cement, the dosage of coal ash is 20-150 parts by weight, the dosage of lime is 50-300 parts by weight, the dosage of water is 50-200 parts by weight, the dosage of lead powder is 0.5-5 parts by weight, the dosage of the water repellent is 1-10 parts by weight, the dosage of the foam stabilizer is 50-200 parts by weight, and the dosage of the water-absorbent resin is 10-100 parts by weight. The good waterproof performance is realized, and the effects of permeation resistance and water repellency can be achieved effectively.
