摘要
地处海洋性气候区的百米碾压混凝土重力坝使用石灰岩人工骨料,综合气候及材料性能,胶凝材料中逐步以石灰石粉代替粉煤灰,经研究温差效应及抗力指标,将温度控制简化到常温浇筑。节约了工程投资,方便了施工,实践证明效果很好。
Artificial limestone aggregates are used in the over 100m high RCC gravity dam located in the maritime climate zone. According to the weather and materials performance, fly ash is gradually replaced by limestone powder in cementing materials. Through analysis of temperature effect and resistance index, temperature control was simplified for pouring at normal temperature, which saves the project investment and facilitates construction. It has been proved by remarkable results.
