| 摘 要： | 本文分析了现有膨胀剂在补偿大体积混凝土收缩方面的不足，介绍了一种双膨胀源膨胀剂。经试验证明。这种膨胀剂既能提供较大的早期膨胀，又能提供稳定的后期膨胀，对补偿大体积混凝土后期的温度收缩十分有利。 |
| 关 键 词： | 大体积混凝土 温度收缩 膨胀剂 补偿 混凝土收缩 后期膨胀 |

| Abstract: | Based on the insufficiency of existing expansive admixture in compensating shrinkage of the mass concrete,a double expansive resources admixture is introduced.This expansive admixture supplies not only enough early expansive change but also steady later stage trace expansion,which is very suit for compensating the temperature shrinkage of the mass concrete. |
| Keywords: | temperature shrinkage compensating shrinkage double expansive resources admixture expansive (ratio) |
