- Abstract
- This study is ASTM C 1260 mortor bar method experiment has been accomplished to estimate the potential of alkai aggregate. Used for testing aggregate samples are forest and crushed aggregate which exceeded alkali-Silica reactivity of KS F 2545 chemical. As the results of experiment confirmed that 10 out of the 20 aggregates samples(50%) are over 0.1% expansions rate standard of potential alkali-Silica reactivity
본 연구는 6개 지역에서 확보한 골재중 KS F 2545 화학적 방법 시험을 통해 알카리 골재반응성 기 준을 초과 하거나 방해석(CaCO3)이 포함된 것으로 확인된 20종을 대상으로 ASTM C 1260 모르타르 봉 방법을 이용한 알칼리골재반응성을 시험하였다. 시험 결과 10(50%)의 골재에서 알칼리골재 잠재반 응성 기준치인 0.1% 이상의 팽창이 발생한 것으로 확인되었다.
