An experimental study was made on optimization of admixtures for the RCC dam of Baise hydro-complex due to the high temperature and high strength construction of the RCC dam as well as the poor deformation resistance and crack resistance of diabase aggregates for the RCC dam. Finally,ZB-1-RCC15 (b)admixtures were selected, which can effectively improve not only the thermal and deformation properties but also the overall crack resistance a-bility of RCC by adding admixtures. Besides,those admixtures were adapted to RCC construction of large area,high strength and high temperature season, which saved the project investment and guaranteed the project quality.
