Alpha gypsum-based grouting material and gypsum-based cold-mixing semi-flexible pavement material
The invention relates to an alpha gypsum-based grouting material which comprises gypsum, cement, S95 slag powder, silica fume, redispersible latex powder, an additive and water, the additives comprise a polycarboxylic acid water reducing agent, a defoaming agent, a vegetable protein retarder and hydroxypropyl methyl cellulose ether; wherein the mass ratio of the gypsum to the cement is (9: 1)-(6: 4); the water cement ratio is 0.40 to 0.55; the doping proportion of the silica fume is 4-10% of the sum of the mass of the cement and the alpha gypsum; the doping proportion of the S95 slag powder is 5-11%; the doping proportion of the redispersible latex powder is 1-1.9%; the doping proportion of the polycarboxylate superplasticizer is 0.5%-1.0%, the doping proportion of the defoaming agent is 0.02%-0.06%, and the doping proportion of the retarder is 0.01%-0.05%; the doping ratio is the ratio of the components to the total mass of the gypsum and the cement; and the content of the hydroxypropyl methyl cellulose ether in the alpha gypsum-based grouting material is 0.1-0.5%. The gypsum-based cold-mixed semi-flexible pavement material prepared by pouring a cold-mixed large-gap matrix asphalt mixture with the grouting material has the characteristics of low shrinkage, low pollution, low energy consumption and the like.
本发明涉及一种α石膏基灌浆料，其包含：石膏、水泥、S95矿渣粉、硅灰、可再分散性乳胶粉、外加剂和水；所述外加剂包括聚羧酸减水剂、消泡剂、植物蛋白类缓凝剂、羟丙基甲基纤维素醚；其中，石膏和水泥质量比为9：1‑6∶4；水灰比为0.40‑0.55；硅灰的掺入比例为水泥与α石膏质量之和的4‑10％；S95矿渣粉的掺入比例为5‑11％；可再分散性胶乳粉的掺入比例为1‑1.9％；聚羧酸减水剂的掺入比例为0.5‑1.0％，消泡剂的掺入比例为0.02‑0.06％，缓凝剂的掺入比例为0.01‑0.05％；掺入比例是以该组分占石膏加水泥总质量的比值；羟丙基甲基纤维素醚在α石膏基灌浆料中的含量为0.1‑0.5％。以该灌浆料灌注冷拌大空隙基体沥青混合料所制备的石膏基冷拌半柔性路面材料，具有低收缩、低污染、低能耗等特点。
