Example Embodiment
[0018] Example 1
[0019] Formula: cement 125kg, desulfurization ash 60kg, fine aggregate 780kg, water-retaining thickening material 25kg, polycarboxylate superplasticizer 0.9kg, sodium lauryl sulfate 0.28kg, accelerator 1.4kg.
[0020] The cement uses ordinary Portland cement P·O 42.5, and the water-retaining thickening material is a mixture of bentonite, first-grade fly ash, hydroxypropyl methyl cellulose ether, and redispersible latex powder. The weight of the four The ratio range is 4.5:5.4:0.13:0.07.
[0021] The preparation method: mixing the early strength water reducing agent, the foaming agent, and the quick-setting agent to obtain the mixed material; mixing the fine aggregate, cement, the water-retaining thickening material, and the desulfurization ash, and then adding the mixed material to mix evenly.
Example Embodiment
[0022] Example 2
[0023] Formula: 130kg cement, 50kg desulfurization ash, 790kg fine aggregate, 25kg water-retaining thickening material, 0.8kg naphthalene series superplasticizer, 0.25kg polyurethane foaming agent, 1.4kg quick-setting agent.
[0024] The cement uses Portland cement P·I 42.5, and the water-retaining thickening material is a mixture of bentonite, first-grade fly ash, hydroxypropyl methyl cellulose ether, and redispersible latex powder. The weight ratio of the four is The range is 4.0:5.8:0.1:0.1.
[0025] The preparation method is the same as in Example 1.
Example Embodiment
[0026] Example 3
[0027] Formula: 140kg of cement, 55kg of desulfurization ash, 800kg of fine aggregate, 20kg of water-retaining and thickening material, 0.8kg of polycarboxylate superplasticizer, 0.23kg of sodium lauryl sulfate, 1.3kg of accelerator.
[0028] The cement used is Portland cement P·Ⅱ42.5. The water-retaining thickening material is a mixture of bentonite, first-grade fly ash, hydroxypropyl methyl cellulose ether, and redispersible latex powder. The weight ratio of the four is 4.9:5.0:0.15:0.05.
[0029] The preparation method is the same as in Example 1.
