Ultra-high performance concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to ultra-high performance concrete and a preparation method thereof. The ultra-high performance concrete provided by the invention comprises the following components in parts by mass: 480-640 parts of cement; 110 to 155 parts of superfine slag powder; 65 to 105 parts of fly ash micro powder; 160 to 210 parts of steel slag micro powder; 95 to 130 parts of silica powder; 1020 to 1180 parts of steel slag sand; 0 to 350 parts of broken stone; 10-20 parts of a polycarboxylic acid water reducing agent; 1-3 parts of a defoaming agent; 10-15 parts of desulfurized gypsum; 9 to 15 parts of sodium hexametaphosphate; 45 to 75 parts of amorphous aluminum oxide; 165 to 190 parts of steel fiber; and 180 to 215 parts of water. The steel slag micro-powder, the steel slag sand, the slag, the fly ash and other solid wastes are used in the ultra-high performance concrete in a large mixing amount, the use amount of cement and quartz sand is saved, the carbon emission is reduced, natural resources are saved, and the production cost is remarkably reduced.
本发明属于混凝土技术领域，具体涉及一种超高性能混凝土及其制备方法。本发明提供的超高性能混凝土，以质量份数计，包括：水泥480～640份；矿渣微粉110～155份；粉煤灰微粉65～105份；钢渣微粉160～210份；硅微粉95～130份；钢渣砂1020～1180份；碎石0～350份；聚羧酸减水剂10～20份；消泡剂1～3份；脱硫石膏10～15份；六磷偏酸钠9～15份；非晶态氧化铝45～75份；钢纤维165～190份；水180～215份。在超高性能混凝土中大掺量使用钢渣微粉和钢渣砂、矿渣、粉煤灰等固废，节约了水泥和石英砂用量，减少了碳排放量，节约自然资源，显著降低生产成本。
