Pumping admixture for non-autoclaved tubular pile
The invention discloses a pumping admixture for a non-autoclaved tubular pile, which belongs to the technical field of building materials. The pumping admixture comprises the following components in percentage by mass: 50-82% of active silicon dioxide, 5-20% of active calcium oxide, 10-30% of activated aluminum oxide, and 3-10% of sulfur trioxide. According to the pumping admixture for the non-autoclaved tubular pile, the water consumption of concrete can be reduced and controlled within 120 kg/m<3>, and meanwhile the three-day strength of the concrete can be kept to reach 80 Mpa; in addition,the concrete can keep good workability and is not easy to harden and separate; and smooth pumping is achieved.
本发明公开了一种免压蒸管桩用泵送掺和料，属于建筑材料技术领域。以质量百分比计算包括成分：活性二氧化硅50‑82％；活性氧化钙5‑20％；活性氧化铝10‑30％；三氧化硫3‑10％。本发明的免压蒸管桩用泵送掺和料能够降低混凝土的用水量，将其控制在120kg/m3以内，同时能够保持混凝土的三天强度达到80Mpa；另外混凝土能保持有良好的和易性，不易板结离析；泵送顺畅。
