Analysis of Crushed stone by Petrographic Examination

쇄석골재의 광물학적 반응성분 분석

In the country, due to short comings of natural aggregates of good quality, it is common to use crushed stones. However, the investigation has not been done on the chemical reaction of crushed stones. This study tested and analyzed the aggregate chemical reaction by petrographic examination(ASTM C 295) for the test aggregates which had been tested by chemical method(ASTM C 289) in the first year. As a result, most of test aggregates didn't show any reaction but many have common deleterious mineral. Therefore, there exists the possibility of chemical reaction in petrogrphic point of view
