Non-autoclaved pipe pile and preparation method thereof
The invention discloses a non-autoclaved pipe pile and a preparation method thereof. The formula of the non-autoclaved pipe pile comprises 33-35% of fine aggregate, 32-36% of coarse aggregate, 0.7-1.0% of an additive, 5-12% of microbead powder and water. The content of concrete in each cubic meter of the non-autoclaved pipe pile is 410-440kg, and the content of cement is 70-90%. The formula of thenon-autoclaved pipe pile concretely comprises 34% of the fine aggregate, 35% of the coarse aggregate, 0.9% of the admixture and 8% of the microbead powder, 420 kg of the concrete and 80% of cement ineach cubic meter of non-autoclaved pipe pile, the fine aggregate is clean natural hard medium-coarse sands or artificial sands, the coarse aggregate adopts gravels or broken pebbles, and the admixture is a high-efficiency naphthalene water reducer. The microbead powder is used for realizing the non-autoclaved process, so that the objective problems of material shortage, high cost and the like aresolved, a series of defects of the traditional non-autoclaved process are overcome, and correspondingly, resources are saved for the country.
本发明公开了一种免蒸压管桩及其制备方法，包括所述免蒸压管桩的配方如下：细骨料33‑35％，粗骨料32‑36％，外加剂0.7‑1.0％，微珠粉5‑12％和水，所述每立方米免蒸压管桩中胶材含量为410‑440kg，水泥70‑90％，包括所述免蒸压管桩的配方如下：细骨料34％，粗骨料35％，外加剂0.9％，微珠粉8％，每立方米免蒸压管桩中胶材420kg，水泥80％，所述细骨料为洁净的天然硬质中粗砂或人工砂，所述粗骨料采用碎石或破碎的卵石，所述外加剂为高效柰系减水剂。本发明使用微珠粉实现免蒸压工艺，不仅解决了材料匮乏、成本高等客观问题，同时弥补了传统免蒸压工艺的一系列不足，相应的也为国家节约了资源。
