Abstract
Creating the proper method of an evaluation test of alkali-silica reactivity is required to promote the usage of recycle aggregate. Therefore, the JIS (Japanese Industrial Standards) draft revision committee of recycled aggregate conducted experiments on the effect of pessimum content which was based on “JIS A 1804 Method of test for production control of concrete—Method of rapid test for identification of alkali-silica reactivity of aggregate”. Also we proposed “the method of rapid test for identification of alkali-silica reactivity of recycled aggregate H” to become a part of “JIS A 5021 Recycled aggregate for concrete—class H” as one of the JIS draft revision plans of 2011.
