碾压混凝土坝与粉煤灰

oller Compacted Coucrete Lam 2nd Riyash

本文内容包括两部分:第一部分介绍碾压混凝土的特性、类型和碾压混凝土坝的发展概况;第二部分专题阐述粉煤灰在碾压混凝土中的作用,并通过试验资料,理论分析了不同类型、不同掺量的粉煤灰对碾压混凝土工作度、强度、抗渗性、水化热等性能的影响。

There a e two parts in this paper: The fist part introduces prop- erties and types of Roller Compacted Concrete (RCC)and Roller Com- pacted Concrete Dam (RCCD), The second one discussss the role of flyash in RCC and with test data and theory analyses of the impact to RCC characterist c of workability, strength, permeability, hydra- tion heat, etc by types and content of flyash.
