쇄석골재의 알칼리-실리카 반응에 관한 실험적 연구 (제4보: 국내산 반응성 골재에 JIS 신속법 적용가능성)

An Experimental Study on the Alkali-Silica Reaction of Crushed Stones (Part4: The Application of the JIS Rapid Test Method to the Several Domestic Reactive Aggregates)

The chemical method and mortar-bar method for identification of the susceptibility to Alkali-Aggregate Reaction (AAR) was established as KS method by referencing the ASTM methods. However, the chemical method requires skilled chemical engineers and aggregates are tested in very severe condition, and on the other hand, the mortar-bar method needs a long time of 3 or 6 months. Judging from this circumstance that the use of crushed stones are increased due to the shortage of natural aggregates, the development and standardization of a new rapid test method is considered essential. The purpose of this paper is to research for the possibility to apply the rapid method, instead of the chemical method and the mortar-bar method with using the several domestic crushed stones.
