中文摘要:
      以低活性钨尾矿为主要原料制备高活性的地聚合物反应前驱物,在直接加水条件下合成地聚合物试样。结果表明,助剂种类对加水一体化合成的地聚合物影响显著,地聚合物反应前驱物制备的最佳试验条件为:助剂种类为氢氧化钾、煅烧时间1h,粉末硅酸钠掺量15%,在此条件下加水一体化合成的地聚合物7天抗压强度达18.78MPa。此外,研究认为高温湿气养护不利于该条件下所制地聚合物强度发展。
英文摘要:
      Preparation of highly active geopolymer reaction precursors with low active tungsten tailings as raw materials and synthesis of geopolymer samples under direct water addition. The results showed that The type of additives has a significant effect on geopolymer by water integration, the optimum conditions for the preparation of geopolymer reaction precursor were as follows: the catalyst was potassium hydroxide, the calcination time was 1h, the content of the powder sodium silicate was 15%, Under this condition, geopolymer has a 7 day compressive strength of 18.78 MPa. In addition,it is concluded that high temperature and moisture conservation is not conducive to the development of polymer strength
