Spraying adjustable setting ultra-high performance concrete
The invention discloses jet adjustable setting ultra-high performance concrete, which is prepared from the following raw materials in parts by weight: 530 to 740 parts of cement, 210 to 420 parts of superfine composite powder, 100 parts of silica fume, 623 to 674 parts of fine sand, 328 to 355 parts of coarse sand, 118 to 196 parts of steel fiber, 11 parts of water reducing agent, 2 parts of defoaming agent and 21 to 37 parts of accelerator. According to the method, the working performance is good, formwork erecting or reinforcing mesh arrangement is not needed when an old building is subjected to injection reinforcement, the setting time can be adjusted, the efficiency of old building reinforcement construction is improved, and meanwhile the water permeability resistance and the contractibility are good.
本发明公开了一种喷射可调凝超高性能混凝土，包括下述重量份的原料：水泥530‑740份、超细复合粉210‑420份、硅灰100份、细砂623‑674份、粗砂328‑355份、钢纤维118‑196份、减水剂11份、消泡剂2份、速凝剂21‑37份。根据本发明，具有良好的工作性能，喷射加固老旧建筑时无需支模或布置钢筋网，凝结时间可进行调整，提高老旧建筑加固施工的效率，同时其具有良好抗水渗透性和收缩性。
