Ultra-high performance concrete for decoration and preparation method thereof
The invention relates to the technical field of concrete, in particular to decorative ultra-high performance concrete and a preparation method thereof. The invention provides ultra-high performance concrete for decoration, which comprises a cementing material, quartz sand, a water reducing agent, a defoaming agent, an expanding agent, fibers and water, the cementing material comprises cement, silica fume, superfine limestone powder, superfine silicon dioxide and quartz powder, and the components are proportioned according to the following weight: 165-350kg/m < 3 > of cement, 0.5-1.5 kg/m < 3 > of silica fume, 0.5-1.5 kg/m < 3 > of superfine limestone powder, 0.5-1.5 kg/m < 3 > of superfine silicon dioxide and 0.5-1.5 kg/m < 3 > of quartz powder. 45-90 kg/m < 3 > of silica fume; 70-90 kg/m < 3 > of superfine limestone powder; 0.1-20 kg/m < 3 > of superfine silicon dioxide; 0.1-50 kg/m < 3 > of quartz powder; 400-550 kg/m < 3 > of quartz sand; and 8-14 kg/m < 3 > of fiber. The invention has the beneficial effects that the admixture material is added, the use amount of cement is small, the strength and durability of the concrete are guaranteed, the shrinkage rate is lower, and the price is lower.
本发明涉及混凝土技术领域，尤其是一种装饰超高性能混凝土及其制备方法。本发明提供的一种用于装饰的超高性能混凝土，包括胶凝材料、石英砂、减水剂、消泡剂、膨胀剂、纤维及水，胶凝材料包括水泥、硅灰、超细石灰石粉、超细二氧化硅和石英粉，各组分按照如下重量进行配比：水泥165‑350kg/m3；硅灰45‑90kg/m3；超细石灰石粉70‑90kg/m3；超细二氧化硅0.1‑20kg/m3；石英粉0.1‑50kg/m3；石英砂400‑550kg/m3；纤维8‑14kg/m3。本发明的有益效果在于添加掺和材料，水泥用量少，保障混凝土强度和耐久性，并且收缩率更低、价格更低。
