High-flowability anti-segregation ultra-high performance concrete and preparation method thereof
The invention relates to a high-flowability anti-segregation ultra-high performance concrete, which is composed of the following components by weight: 350-450 parts of cement; 90 to 130 parts of silica fume; 110 parts to 160 parts of superfine mineral powder; 850 to 1100 parts of quartz sand; 12 parts to 22 parts of a high-performance water reducing agent; fibers: 12 to 32 parts; 1.5 to 3.5 parts of a thickening agent; 3.5 parts to 5.5 parts of an anti-segregation agent; 5 to 10 parts of nano silicon dioxide; 2 to 5 parts of graphene nanoplatelets; 3 to 8 parts of a whisker material; and 10 to 20 parts of active powder. By elaborately blending various special materials, the strength, crack resistance, impermeability, freezing resistance and the like of the concrete are greatly improved, and the requirements of various high-standard building structures are met.
本发明涉及一种高流动抗离析超高性能混凝土，由以下重量份的组分组成：水泥：350份至450份；硅灰：90份至130份；超细矿粉：110份至160份；石英砂：850份至1100份；高性能减水剂：12份至22份；纤维：12份至32份；增稠剂：1.5份至3.5份；抗离析剂：3.5份至5.5份；纳米二氧化硅：5份至10份；石墨烯微片：2份至5份；晶须材料：3份至8份；活性粉末：10份至20份。本发明通过精心调配多种特殊材料，大幅提高了混凝土的强度、抗裂性能、抗渗性和抗冻性等，满足各类高标准建筑结构需求。
