| Abstract: | This article discusses some problems which impact the construction of darn or quality of concrete that existing in the RCC dam construction techniques, such as the relationship between the intermingled quantity of fly ash and the strength of age, the impact to the VC value and coagulation time caused by concrete disturbance and different environments, the impact to concrete strength by replacing the fly ash in binder of concrete material to artificial sand, and the characteristics of water consumption of dif- ferent fly ash in neat cement paste and mortar and so on, and put forward the author＇s point of view as well. |
