摘要
Abstract
As limited by the objective circumstances, the metamorphosed quartz sandstone with potential alkali reactivity has to be adopted to the artificial aggregate for the concrete of the arch dam for Jinping I Hydropower Station. In accordance with the results from the testing made on the actual measures for the inhabitation of the concrete alkali-aggregate response, it is indicated that the expansive deformation from the alkali-aggregate response of the metamorphosed quartz sandstone in the concrete can be effectively inhibited by the engineering measures such as composited aggregate, mixing with high fly ash content of 35% , control of total alkali content, etc. .关键词
