| Abstract: | A method to assess the effectiveness of mineral admixtures in suppressing the alkali-silica reaction was presented.Based on accelerated mortar bar test,the method improve the storage condition of this test.Modified test was applied in suppressing the alkali-silica reaction of slate aggregate and 1% pyrex glass aggregate,and the result was compared with that of accelerated mortar bar test.The results confirmed modified method could reflect the rule of fly ash in suppressing the alkali-silica reaction.The final conclusion of the two methods for the two aggregates was similar,which could be used to assess the effectiveness of mineral admixtures in suppressing alkali-silica reaction. |
