The Possibility of Alkali-Aggregate Reaction of High Strength Concrete by Concrete Bar Test

콘크리트 시험체 시험법을 통한 고강도 콘크리트의 알칼리골재 반응성

The deterioration of concrete due to alkali-aggregate reaction is dependent on the total alkali content per unit volume of concrete. It was reported that the expansion of high alkali concrete with the reactive aggregate increased easily due to high alkali of concrete with the reactive aggregate increased easily. And it has been confirmed that the addition of pozzolanic material prevents the concrete with reactive aggregate from deterioration caused by alkali-aggregate reaction. It is the aim of this study to provide the fundamental data on the possibility of alkali-aggregate reaction of high strength concrete and its preventing and repair technic.
