Mining sprayed concrete based on coal gangue and preparation method thereof
The invention relates to the technical field of sprayed concrete, and particularly provides mine sprayed concrete based on coal gangue and a preparation method of the mine sprayed concrete. The sprayed concrete comprises a component A and a component B in a weight ratio of 100: (3-9), wherein the component A comprises the following components in parts by weight: 100-140 parts of cement, 135-150 parts of coal gangue, 50-70 parts of water, 15-20 parts of an admixture, 1-5 parts of calcium formate, 4-5 parts of a water reducing agent and 1-2 parts of an air entraining agent; the component B comprises the following components in parts by weight: 4-10 parts of polyaluminum sulfate, 1-9 parts of triisopropanolamine, 1-4 parts of aluminum sulfate octadecahydrate, 1-4 parts of ethylene glycol, 2-5 parts of nano aluminum hydroxide and 3-5 parts of triisopropanolamine octanoate. The sprayed concrete provided by the invention still has better mechanical properties while using the coal gangue as the aggregate.
本申请涉及喷射混凝土技术领域，具体提供了一种基于煤矸石的矿用喷射混凝土及其制备方法。其中，所述喷射混凝土包括重量比为100：(3‑9)的组分A和组分B；其中，A组分包括以下重量份数的组分：水泥100‑140份，煤矸石135‑150份，水50‑70份，掺合料15‑20份，甲酸钙1‑5份，减水剂4‑5份，引气剂1‑2份；B组分包括以下重量份数的组分：聚合硫酸铝4‑10份，三异丙醇胺1‑9份，十八水合硫酸铝1‑4份，乙二醇1‑4份，纳米氢氧化铝2‑5份，辛酸三异丙醇胺酯3‑5份。本申请提供的喷射混凝土在使用煤矸石作为骨料的同时，依旧具有较佳的力学性能。
