Underwater pile foundation machine-made sand self-compacting concrete and preparation method thereof
The invention discloses underwater pile foundation machine-made sand self-compacting concrete and a preparation method thereof. The underwater pile foundation machine-made sand self-compacting concrete comprises following components by mass: 12.00 to 16.00 parts of cement, 0.82 to 1.65 parts of nano-scale spherical siliceous powder, 2.88 to 3.70 parts of micron-sized spherical siliceous powder, 0.82 to 2.05 parts of high-activity siliceous-calcareous powder, 9.96 to 10.93 parts of machine-made broken stone A, 23.23 to 25.51 parts of machine-made broken stone B, 35.62 to 39.45 parts of machine-made sand, 0.30 to 0.62 part of an additive and 7.62 to 8.02 parts of water. According to the invention, high-quality raw materials are preferably selected, and indexes such as cement fineness, setting time and standard consistency are controlled, so that the cement meets the requirement of setting time of concrete for 10-15 hours under the action of an additive, and is suitable for construction of underwater pile foundation concrete without flowing water and with the length of 0-70m.
本发明公布了一种水下桩基机制砂自密实混凝土及其制备方法，混凝土各组分的质量比为：水泥12.00‑16.00、纳米级球体硅质粉0.82‑1.65、微米级球体硅质粉2.88‑3.70、高活性硅钙质粉0.82‑2.05、A机制碎石9.96‑10.93、B机制碎石23.23‑25.51、机制砂35.62‑39.45、外加剂0.30‑0.62、水7.62‑8.02，本发明优选优质原材料，对于水泥细度、凝结时间、标准稠度等指标的控制，使得水泥在外加剂作用下满足混凝土10‑15小时凝结时间的要求，适用于无流动水、0‑70m长的水下桩基混凝土施工。
