| 摘 要： | 大体积混凝土中外加剂的应用十分普遍，并且经常是多种外加剂的复合使用。通过论述减水剂、缓凝剂及膨胀剂单独使用及复合使用对大体积混凝土性能的影响以及大体积混凝土中广泛应用的矿物掺合料对三种外加剂使用效果的影响，对外加剂在大体积混凝土中的正确应用有重要意义。 |
| 关 键 词： | 减水剂 缓凝剂 膨胀剂 大体积混凝土 水化热 |

| Abstract: | Additives have been used widely in the mass concrete and often compounded with other admixtures. Water-reducers, retarders and expansive agents are the most widely used sorts in the mass concrete. In this paper, the influences of these three sorts of admixtures on the mass concrete were introduced not only used solely but also used compounded. Furthermore,the influences of the mineral admixtures on the chemical admixtures have been discussed,because the mineral admixtures have been used widely in the mass concrete. These results would give some valuable guides to the applications of the chemical admixture in the mass concrete. |
