| 摘 要： | 大体积混凝土工程中,混凝土配合比设计应以控制温度差为首要目标,充分利用控制水泥用量、掺加矿粉和粉煤灰、延长混凝土设计龄期、选用缓凝型高效减水剂等方法,降低水化热、延缓和削弱水化热峰值,减少混凝土温度差,避免混凝土温度裂缝的产生。 |
| 关 键 词： | 大体积 配合比 温度差 裂缝 |

| Abstract: | During mass concrete engineering,the design of concrete mix ratio should take temperature difference control as the chief aim,make full use of the methods such as controlling amount of cement,mixing mineral powder and coal-ash powder,prolonging concrete design age,choosing low-dosage and set-retarding high-performance superplasticizer,reduce hydration heat,stave and weaken peak of hydration heat,reduce temperature difference of concrete and avoid concrete temperature cracks. |
| Keywords: | mass concrete mix ratio temperature difference crack |
