【Abstract】 The dynamics of alkali silica reaction (ASR) and some major parameters of testing method for determining ASR reactivity of aggregate were systematically investigated,which included reaction temperature,period,concentration of alkali solution,cement to aggregate ratio,and alkali content of cement etc. The suitable conditions of testing method could be defined according to the results, and the theoretical bases of identifying the major parameters in a new testing method for determining the ASR reactivity of siliceous aggregates could also be established.更多还原
