| 摘 要： | 首先通过不同掺量赤砂糖缓凝剂在室温和高温条件下的缓凝效果试验确定最佳的赤砂糖缓凝剂掺量范围,接着通过其他补充外加剂选择试验选定以UNF-5H高效减水剂和赤砂糖缓凝剂主体,外加吉林木钙普通减水剂、X.P引气剂的组合为最佳,再通过UNF-5H高效减水剂、赤砂糖缓凝剂、吉林木钙普通减水剂、X.P引气剂组合配合比试验确定各成份的最佳含量,最后通过最佳组合配合比高效外加剂质量性能的稳定性试验确定以赤砂糖缓凝剂和UNF-5H高效减水剂主体的高效外加剂溶液呈弱碱环境下,其质量性能在保质期范围内能保持不变.

| Abstract: | The optimal mixing amount range of brown granulated sugar retarder was determined by the retarding effect of difference mixing amount under the condition of room temperature and high temperature.After the additive test,UNF-5H water reducing agent and brown granulated sugar retarder was choose as the main composition with the addition of X.P air-entraining agent and Jiling ordinary calcium lignosulfonate water reducing agent,and the optimum mix ratio was designed after the formulation test.The stability expe... |
