CF120 ultrahigh-strength concrete and preparation method thereof
The invention discloses CF120 ultrahigh-strength concrete and a preparation method thereof. The concrete comprises the following raw materials in parts by weight: 500-600 parts of cement; 750 to 860 parts of sand; 1200 to 1350 parts of broken stone; 90 to 100 parts of fly ash; 75 to 83 parts of straw ash; 37 to 50 parts of silica fume; 145 to 160 parts of water; 15 to 20 parts of a water reducing agent; 15 to 20 parts of an exciting agent; 3-5 parts of a defoaming agent; 12-16 parts of a shrinkage reducing agent; 23 to 28 parts of CaCO3 crystal whisker; 20 to 30 parts of polyvinyl formal acetal; 20 to 30 parts of titanium dioxide loaded fiber; the titanium dioxide loaded fibers are prepared by modifying fibers with titanium dioxide; the fibers comprise at least one of steel fibers or polypropylene fibers. The CF120 ultrahigh-strength concrete provided by the invention has relatively high compressive strength and breaking strength, and the situation that the concrete generates cracks is also reduced.
本申请公开了一种CF120超高强混凝土及其制备方法，所述混凝土按重量份包括如下原料：水泥500‑600份；砂750‑860份；碎石1200‑1350份；粉煤灰90‑100份；秸秆灰75‑83份；硅灰37‑50份；水145‑160份；减水剂15‑20份；激发剂15‑20份；消泡剂3‑5份；减缩剂12‑16份；CaCO3晶须23‑28份；聚乙烯醇缩甲乙醛20‑30份；二氧化钛负载纤维20‑30份；所述二氧化钛负载纤维由二氧化钛对纤维改性制得；所述纤维包括钢纤维或聚丙烯纤维的至少一种。本申请提供的CF120超高强混凝土具有较高的抗压强度、抗折强度，而且还降低混凝土产生裂缝的情况。
