Low-temperature applicable concrete
The invention belongs to the field of building materials and relates to low-temperature applicable concrete. The concrete is prepared from the following raw materials in parts by weight: 300 to 300 400 parts of Portland cement; 50 to 50 60 parts of mineral powder; 40-60 parts of silica fume; 2-3 parts of 50 parts of igneous rock fibers; 10-20 parts of redispersible rubber powder; 5-10 parts of triisopropanolamine; 5-8 parts of nano silicon particles; 0.2-0.3 part of triethanolamine; 7-13 parts of calcium nitrite; 20-30 parts of nano starch; 20-30 parts of ethylene glycol; 10-20 parts of laurylsodium sulfate; 2-4 parts of calcium lignosulphonate; and 100-200 parts of water. After being formed, the concrete disclosed by the invention has better early and later strength and excellent anti-freezing performance.
本发明涉及建材领域，具体涉及一种低温适用混凝土，由以下重量份的原料制备而成：硅酸盐水泥300～400份、矿粉50～60份、硅灰40～50份、火成岩纤维2～3份、可再分散性胶粉10～20份、三异丙醇胺5～10份、纳米硅颗粒5～8份、三乙醇胺0.2～0.3份、亚硝酸钙7～13份、纳米淀粉20～30份、乙二醇20～30份、十二烷基硫酸钠10～20份、木质素磺酸钙2～4份、水100～200份。本发明的混凝土成型后具有较好的早后期强度，其而具有优良的抗冻性能。
