[0042] The preparation process of the novel desulfurization ash-based cementitious material of the present invention is as follows: first, the block fly ash is crushed to a particle size below 5 mm; then the fly ash, desulfurization ash, boiler ash, and S95 grade mineral powder are dried until the moisture content is not greater than 1%; the dried fly ash, desulfurization ash, boiler ash, S95 grade mineral powder and cement clinker, H 4000 The masterbatch surfactants are measured according to the mixing ratio, and the planetary ball mill is used to blend and mechanically activate at a speed of 250-350r / min for 30-35min. After passing through a 45μm square hole sieve, the sieve residue is not more than 10%. It can be obtained.
[0043] where H 4000 The preparation method of the masterbatch surfactant is as follows: mix desulfurized gypsum, sodium carbonate, sodium silicate, and sodium water reducer in proportion to prepare a solid mixture, and spray liquid triethanolamine and p...
Embodiment 1
[0045] The gelling material is proportioned according to the mass parts in Table 1, wherein H 4000 The ratio of masterbatch surfactant is 82 parts of desulfurized gypsum, 2 parts of naphthalene water reducer, 5 parts of sodium carbonate, 5 parts of sodium silicate, 3 parts of polymer polyol, and 3 parts of triethanolamine.
[0046] The materials are measured and ground to make cementitious materials. According to the "Cement Mortar Strength Test Method" (GB177-5), the cement mortar strength test is carried out, and the initial setting time and final setting time of each ratio are tested respectively. After standard curing Test its 3d, 28d, 120d compressive strength and flexural strength.

Embodiment 2
[0053] (1) The cementitious material is proportioned according to the following mass parts: 15 parts of desulfurization ash, 56 parts of S95 grade mineral powder, 7 parts of fly ash, 4 parts of boiler ash, 15 parts of 42.5 cement clinker, H 4000 Masterbatch surfactant 3 parts. where H 4000 The ratio of masterbatch surfactant is 82 parts of desulfurized gypsum, 2 parts of naphthalene water reducer, 5 parts of sodium carbonate, 5 parts of sodium silicate, 3 parts of polymer polyol, and 3 parts of triethanolamine.
[0054] (2) Mix the cementitious material, desulfurized ash, stones, and stone powder in a certain proportion, put them into the cement mortar mixer in sequence, dry mix for 1 to 2 minutes, add additional water (calculated on a dry basis), and wet mix for 3 to 2 minutes. 5min, the mixture was obtained.
[0055] (3) Put the mixture into the mold of Φ10×5cm, mold it on the press and release the film. The molding pressure is 160KN. During the molding process, it should ...
