Sprayed concrete for roadway
The invention provides sprayed concrete for a roadway. The sprayed concrete is prepared from the following raw materials in parts by weight: 80-120 parts of cement, 40-60 parts of superfine aggregate, 80-100 parts of fine sand, 10-20 parts of fibers, 6-12 parts of rubber powder, 7-10 parts of nano aluminum oxide, 3-8 parts of polyacrylamide, 8-14 parts of an MK-1 reinforcing agent, 1.5-5 parts of a water reducing agent, 6-10 parts of a flame retardant and 10-18 parts of an accelerator. According to the invention, an inorganic-organic co-hybrid polymer dispersion group system is formed on the basis of the principle of an inorganic-organic ultrafine powder assembly, coating and dispersion system, so that moderate toughness and rigidity can be achieved, excellent guniting material indexes such as high adhesion, cracking resistance, impermeability, reinforcement and support and the like are achieved, and the concrete also has relatively strong toughness, ductility, heat insulation and shock absorption performance.
本发明提供了一种用于巷道的喷射混凝土，包括以下重量份数的原料：水泥80～120份，超细骨料40～60份，细沙80～100份，纤维10～20份，橡胶粉6～12份，纳米氧化铝7～10份，聚丙烯酰胺3～8份，MK‑1增强剂8～14份，减水剂1.5～5份，阻燃剂6～10份，速凝剂10～18份。本发明以无机‑有机超细粉体组装、包覆、分散体系原理，形成无机‑有机共杂聚合物分散组配团系，可达到中度韧度刚性，具有高粘附性、防开裂、抗渗、加固支撑等优秀的喷浆材料指标，还具有很较强的韧性、延性以及隔热、减震的性能。
