Super high-rise pump concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses super high-rise pump concrete and a preparation method thereof. The super high-rise pump concrete comprises the following raw materials in parts by weight: 40-45 parts of cement, 80-100 parts of coarse aggregate, 60-70 parts of fine aggregate, 12-18 parts of water, 5-15 parts of a lubricating material, 15-20 parts of fly ash, 2-5 parts of silica fume, 0.5-1 part of an air entraining agent, 2-5 parts of fly ash hollow microspheres and 0.5-1 part of an auxiliary agent, the auxiliaries comprise a water reducing agent, a slump retaining agent and a retarder. The super high-rise pump concrete prepared according to the formula has excellent fluidity, is free of segregation and bleeding in the pressure pumping process, and is very small in time loss.
本申请涉及混凝土技术领域，具体公开了一种超高层泵送混凝土及其制备方法。超高层泵送混凝土，包括以下重量份的原料：水泥40‑45份、粗骨料80‑100份、细骨料60‑70份、水12‑18份、润滑料5‑15份、粉煤灰15‑20份、硅灰2‑5份、引气剂0.5‑1份、粉煤灰空心微珠2‑5份和助剂0.5‑1份；所述助剂包括减水剂、保坍剂和缓凝剂。采用本申请的配方制得的超高层泵送混凝土具有优异的流动性的同时在加压泵送的过程中不离析、不泌水，且经时损失很小。
