Abstract: Alkali-Silica Reaction(ASR) occurs for a long term. In the repairs of ASR damaged concrete structure, it needs to know the residual reactivity in aggregates. In this paper, the reactivity in aggregates taken from ASR damaged concrete prisms had been stored for 11-14 years, was investigated by chemical test method and expansion measurements of concrete prisms were made with the aggregates. In chemical method, dissolved silica(Sc) of aggregates taken from ASR damaged concrete prisms differed from that of original aggregates. The expansions of the concrete prisms that were adjusted in the quantity of 9 kg/m^3 alkali were different by the kinds of rocks and the locality of aggregates. And also, it was different from the past expansions for ll-14years.
