| 摘 要： | 大朝山水电站是正在开工兴建的国家重点大型工程。枢纽工程中的拦河坝选定全断面碾压混凝土重力坝，其碾压混凝土掺合料的选择是本工程的筑坝关键问题。经过对６种掺合料的比选，最后选用磷矿渣与凝灰岩混磨作为掺合料。经大朝山水电站工程实际应用，证明其技术上是成功的。经济效益是显著的，此项成果成为缺少粉煤灰的地区修筑碾压混凝土开发了新的料源。

| Abstract: | Dachaoshan Hydro Station is a country's key large scale project and its dam across river is a full section RCC gravity dam. The selection of the admixture for its roller compacted concrete is the key to the construction of this project. Through the comparisons on six admixtures, a new admixture with good properties, which is gained by mixing the phosphate slag and tuff, has been finally selected. This new admixture has gained outstanding technical achievements and economic benefits. It also provides a new material source for those regions with the shortage of flyash when such regions build RCC dam. |
