Non-autoclaved high-strength concrete pipe pile and preparation method thereof
The invention discloses a non-autoclaved high-strength concrete pipe pile. In the pipe pile concrete, the high-strength concrete per cubic meter comprises the following raw materials: 580-720 kg of large stone, 600-800 kg of small stone, 650-930 kg of machine sand, 300-400 kg of cement, 19-39 kg of an additive, 40-60 kg of water, and micro-bead powder accounting for 24-36% of the total amount of the concrete. The invention further discloses a preparation method of the non-autoclaved high-strength concrete pipe pile. The prestressed high-strength concrete pipe pile is prepared without an autoclaving curing procedure, so that resources are saved, energy consumption is reduced, and economic benefits of enterprises are improved.
本发明公开了一种免蒸压的高强混凝土管桩，管桩混凝土中每立方米高强混凝土包括以下组分的原料：大石580‑720kg，小石600‑800kg，机砂650‑930kg，水泥300‑400kg，外加剂19‑39kg，水40‑60kg，微珠粉占混凝土总量的24‑36％。本发明还公开了一种免蒸压的高强混凝土管桩的制备方法。本发明未使用压蒸养护的工序来制备预应力高强混凝土管桩，节省了资源，减少了能源消耗，提高了企业的经济效益。
