Sprayed concrete admixture and production process
The invention discloses a sprayed concrete admixture. Comprising the following components in parts by weight: 15 parts of polymerized vinyl alcohol phenolic resin, 7 parts of dodecyl phosphate diethanolamine salt, 50 parts of calcium hydroxide, 10 parts of CaAl-layered double hydroxide, 20 parts of aluminum sulfate, 7 parts of lithium carbonate, 0.5 part of basalt fiber, 0.5 part of aramid fiber, 3 parts of sulfonated modified iso-tridecanol polyoxyethylene ether, 50 parts of metakaolin and 10 parts of microcrystalline silicon powder. The concrete is prepared from, by weight, 18 parts of bauxite powder, 1.2 parts of silicon carbide nano powder, 10 parts of spodumene powder, 2 parts of polyacrylamide fibers, 1 part of polycarboxylate superplasticizer and 0.8 part of phenolic resin. By using the admixture, the springback rate of sprayed concrete can be effectively reduced, the one-time spraying thickness is increased, and the early strength is improved.
一种喷射混凝土掺合料，包括以下重量份数的组分：聚合乙烯醇酚醛树脂15份、十二烷基磷酸酯二乙醇胺盐7份、氢氧化钙50份、CaAl‑层状双金属氢氧化物10份、硫酸铝20份、碳酸锂7份、玄武岩纤维0.5份、芳纶纤维0.5份、磺化改性异构十三醇聚氧乙烯醚3份、偏高领土50份、微晶硅粉10份、铝矾土矿粉18份、碳化硅纳米粉1.2份、锂辉石粉10份、聚丙烯酰胺纤维2份、聚羧酸减水剂1份、酚醛树脂0.8份。通过本发明掺合料的使用可以有效降低喷射混凝土回弹率、提高一次喷射厚度、提高早期强度。
