Ultra-light high-strength concrete and preparation method thereof
The invention discloses ultra-light high-strength concrete, which is prepared from the following raw materials in parts by weight: 600-800 parts of cement, 100-300 parts of silica fume, 140-220 parts of hollow glass micro-beads, 120-400 parts of ceramsite, 4-14 parts of carbon fibers, 20-60 parts of nano zirconium oxide, 18-27 parts of a water reducing agent and 120-180 parts of water. According to the method, the components are added into a stirring pot according to a certain sequence and uniformly stirred to form the light high-strength concrete with the volume weight of about 1500 kg/m<3>, wherein the strength can reach more than 90MPa after forming and curing for 28 d. According to the invention, the micron-order filling effect of each raw material component is fully utilized, the concrete strength is greatly improved, the dead weight of the concrete structure can be effectively reduced by 35%, and the use value is wide.
本发明公开了一种超轻质高强混凝土，其原料按照重量份数计：水泥600～800、硅灰100～300、空心玻璃微珠140～220、陶粒120～400、碳纤维4～14、纳米氧化锆20～60、减水剂18～27和水120～180；按照一定顺序加入搅拌锅拌匀后即可形成容重为1500kg/m3左右的轻质高强混凝土，经成型养护28d后强度可达90MPa以上；本发明充分利用各原材料组分微米级填充效应，极大提升了混凝土强度，且可有效降低混凝土结构自重35％，具有广泛的使用价值。
