Composite cementing material for curing loess as well as preparation method and application of composite cementing material
The invention relates to the technical field of building materials, and particularly discloses a composite cementing material for curing loess as well as a preparation method and application of the composite cementing material. The composite cementing material for curing the loess is prepared from the following components in parts by mass: 35 to 40 parts of slag powder, 35 to 40 parts of steel slag powder, 10 to 15 parts of diabase powder, 4 to 8 parts of semi-hydrated phosphogypsum, 4 to 8 parts of ash calcium powder, 0.03 to 0.08 part of anionic surfactant, 0.05 to 0.15 part of ammonium polyacrylate, 0.5 to 1 part of exciting agent and 0.5 to 1 part of beta-naphthalenesulfonate formaldehyde condensate. The composite cementing material for curing the loess is used for curing the loess, the compactness of the cured loess can be increased, the compressive strength of the cured loess can be increased, the anti-freezing performance, the water resistance and the damp-heat aging resistance of the cured loess can be improved, and the composite cementing material is low in cost, small in dosage, simple in preparation method and suitable for industrial production. And the cost of curing the loess can be effectively reduced.
本发明涉及建筑材料技术领域，具体公开一种用于黄土固化的复合胶凝材料及其制备方法和应用。所述用于黄土固化的复合胶凝材料，包括以下质量份数的组分：矿渣粉35‑40份，钢渣粉35‑40份，辉绿岩粉10‑15份，半水磷石膏4‑8份，灰钙粉4‑8份，阴离子表面活性剂0.03‑0.08份，聚丙烯酸氨0.05‑0.15份，激发剂0.5‑1份，β‑萘磺酸盐甲醛缩合物0.5‑1份。本发明提供的用于黄土固化的复合胶凝材料用于固化黄土可增加固化黄土的密实度，增加固化黄土的抗压强度，提升固化黄土的抗冻、耐水和耐湿热老化的性能，且该复合胶凝材料的成本低、用量少、制备方法简单，能有效降低固化黄土的成本。
