Iron tower foot high-strength shrinkage-free secondary pouring filling material and pouring process thereof
The invention relates to a high-strength shrinkage-free secondary pouring filling material for an iron tower foot and a pouring process of the high-strength shrinkage-free secondary pouring filling material. Wherein the secondary pouring filling material comprises the following components in parts by weight: 75-80 parts of cement, 305-320 parts of fine aggregate, 254-262 parts of modified hydrophobic mineral powder, 295-310 parts of short and fine steel fibers, 40-50 parts of a dispersing agent, 35-42 parts of an early strength agent, 15-20 parts of a shrinkage regulator, 1-2 parts of an air entraining and water reducing agent and 60-65 parts of magnetized water; the dispersing agent comprises a hydroxyl-containing acrylate monomer and borax in a mass ratio of 1: (1.2-1.4); the modified hydrophobic mineral powder comprises hydrophobic mineral powder modified and grafted with hydroxyl. The iron tower base has the effect that the high-strength iron tower base is obtained under the condition of no vibration.
本申请涉及一种铁塔脚高强无收缩二次浇筑填充材料及其浇筑工艺，其中二次浇筑填充材料包括如下重量份的组分：水泥75‑80份、细骨料305‑320份、改性疏水矿物粉254‑262份、短细钢纤维295‑310份、分散剂40‑50份、早强剂35‑42份、收缩调节剂15‑20份、引气减水剂1‑2份、磁化水60‑65份；分散剂包括质量比为1：（1.2‑1.4）的含羟基丙烯酸酯单体和硼砂；改性疏水矿物粉包括改性接枝有羟基的疏水矿物粉。本申请具有使得在不振捣情况下得到高强度的铁塔底座的效果。
