Pumping prestressed concrete pipe pile and preparation method thereof
The invention relates to the technical field of building materials, in particular to a pumping prestressed concrete pipe pile and a preparation method thereof. The concrete pipe pile comprises the following components: a liquid material and a dry material, the liquid material comprises the following raw material components: a water reducing agent, a slump retaining agent, a defoaming agent, a stabilizer, a modifier, a thickening time control agent, a polymer emulsion, a viscosity reducer, a preservative and water; the dry material is prepared from the following raw material components: Portland cement, glass powder, silica fume, glass sand, silicon dioxide-ceramic high-strength composite micro powder, ground fine sand, gravel, fibers and water. The problems of poor workability, large bleeding amount, large viscosity, low compressive strength, long setting time and the like caused when a polycarboxylic acid additive and a regenerated glass material are applied to production of the pumped prestressed concrete pipe pile can be solved, the defects of reduced compressive strength, too long setting time and the like of concrete are overcome, and the requirements of relevant standards of the concrete pipe pile are met. And the price is relatively affordable.
本发明涉及建筑材料技术领域，特别涉及一种泵送预应力混凝土管桩及其制备方法。该混凝土管桩的组分包括液料和干料；液料包括以下原料组分:减水剂、保坍剂、消泡剂、稳定剂、改性剂、调凝剂、聚合物乳液、降粘剂、防腐剂、水；干料包括以下原料组分:硅酸盐水泥、玻璃粉、硅灰、玻璃砂、二氧化硅‑陶瓷高强复合微粉、磨细砂、碎石、纤维、水。本发明可改善聚羧酸添加剂和再生玻璃材料应用于泵送预应力混凝土管桩生产中时，带来的和易性差、泌水量大、粘度大、抗压强度低、凝结时间长等问题，并弥补混凝土抗压强度降低和凝结时间偏长等缺陷，使混凝土管桩相关标准的规定，且价格相对实惠。
