Non-autoclaved high-strength concrete pipe pile and preparation process thereof
The invention discloses a non-autoclaved high-strength concrete pipe pile and a preparation process thereof, belongs to the technical field of constructional engineering materials, and solves the technical problem that high-pressure steam curing is needed in the steam curing process of a high-strength concrete pipe pile in the prior art. The high-strength concrete in each cubic meter of the tubular pile concrete is prepared from the following raw materials: 580 to 720 kg of large stone, 600 to 800 kg of small stone, 720 to 920 kg of machine sand, 280 to 380 kg of cement, 23 to 43 kg of an additive, 40 to 60 kg of water and 120 to 160 kg of microbead powder. According to the tubular pile and the preparation process thereof, a high-energy-consumption high-pressure steam curing process can be omitted, the strength of the produced concrete tubular pile can reach C120, resources are saved, and energy loss is reduced.
本发明公开了一种免蒸压的高强混凝土管桩及其制备工艺，属于建筑工程材料技术领域，解决了现有技术中高强混凝土管桩蒸汽养护过程中需高压蒸汽养护的技术问题，本发明的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720‑920kg，水泥280‑380kg，外加剂23‑43kg，水40‑60kg，微珠粉120‑160kg。本发明的管桩及其制备工艺可不经过高能耗的高压蒸汽养护的过程，生产的混凝土管桩可达到C120的强度，实现了资源的节约，降低了能源的损耗。
