High-strength solid-waste-based magnesium phosphate grouting slurry and preparation method thereof
The invention discloses a high-strength solid-waste-based magnesium phosphate grouting slurry and a preparation method thereof. The solid-waste-based magnesium phosphate grouting slurry is prepared from the following raw materials: 8-13 parts of red mud, 8-14 parts of shell powder, 8-14 parts of coral sand, 9-10 parts of fly ash, 6-8 parts of carbide slag, 5-6 parts of mineral slag, 4-5 parts of steel slag, 0-3 parts of boric oxide, 2-3 parts of borax and 1.5-2 parts of a chitosan film. The magnesium phosphate cementing material comprises the following raw materials: 8-13 parts of a C4AF solid solution, 13-16 parts of magnesium oxide and 5-6 parts of phosphate; the composite admixture consists of an admixture I and an admixture II; the admixture I comprises the following raw materials in parts by weight: 0.3-2 parts of a water reducing agent and 5-10 parts of xanthan gum; the admixture II is prepared from the following raw materials in parts by weight: 0.2-3.8 parts of chopped fibers and 1-2 parts of roasted hydrotalcite; the use amount of the seawater meets the requirement that the water-binder ratio is 0.8: 1-1.5: 1. The particle size interval of part of the components is red mud lt; the shell powder accounts for 120-150 [mu] m, and the fly ash accounts for 1t; the particle size is 45 microns, the carbide slag is 10-50 microns, the slag is 0-60 microns, and the steel slag is 0-50 microns The invention aims to prepare the high-strength solid waste-based magnesium phosphate grouting slurry from industrial solid wastes, shallow sea waste materials and seawater, and the high-strength solid waste-based magnesium phosphate grouting slurry can be applied to the field of prevention and control of engineering disasters of coast, island reef, water conservancy and the like.
本发明公开了一种高强固废基磷酸镁注浆浆液及制备方法，固废基材料原料为：赤泥8‑13份，贝壳粉8‑14份，珊瑚砂8‑14份，粉煤灰9‑10份，电石渣6‑8份，矿渣5‑6份，钢渣4‑5份，氧化硼0‑3份，硼砂2‑3份，壳聚糖膜1.5‑2份；磷酸镁胶凝材料原料为：C4AF固溶体8‑13份，氧化镁13‑16份，磷酸盐5‑6份；复合外加剂由外加剂I、外加剂II组成，外加剂I原料为：减水剂0.3‑2份，黄原胶5‑10份；外加剂II原料为：短切纤维0.2‑3.8份，焙烧水滑石1‑2份；海水用量满足水胶比为0.8:1‑1.5:1。部分组分粒径区间为：赤泥<75μm、贝壳粉120‑150μm、粉煤灰<45μm、电石渣10‑50μm、矿渣0‑60μm、钢渣0‑50μm。本发明旨在利用工业固废、浅海废材及海水，制备一种高强固废基磷酸镁注浆浆液，能应用于海岸、岛礁、水利等工程灾害防控领域。
