Ultra-high performance concrete with low cement content and preparation method thereof
The invention discloses ultra-high performance concrete with low cement content and a preparation method thereof, and belongs to the technical field of concrete materials. The ultra-high performance concrete with low cement content is prepared from the following raw materials in parts by weight: 112 to 562 parts of superfine quartz powder, 188 to 638 parts of cement, 170 parts of silica fume, 200 parts of fly ash, 990 parts of aggregate, 200 parts of water and 30 parts of water reducing agent. According to the invention, the superfine quartz powder is added to replace cement, so that the content of cement clinker in the concrete can be reduced to 188kg/m < 3 > (the cement replacement amount reaches 75%) on the premise of keeping good mechanical properties.
本发明公开了一种低水泥含量超高性能混凝土及其制备方法，属于混凝土材料技术领域。本发明的低水泥含量超高性能混凝土，包括以下重量份数的原料：超细石英粉112～562份、水泥188～638份、硅灰170份、粉煤灰200份、骨料990份、水200份和减水剂30份。本发明通过添加超细石英粉替代水泥，在保持良好的力学性的前提下，可以将混凝土中水泥熟料含量降低到188kg/m3(水泥替代量达到75％)。
