Abstract

This study is based on the evaluation of a single component injection type adhesive repair material and a new 2 component type used in leakage of underground concrete structures. The studies showed that based on different mix ratio of the 2 component type adhesive sealant comprised of an asphalt main and latex mixture agent the viscosity of the material compound differed significantly. Based on a permeability testing, injection and economic efficiency, and performance, the appropriate ratio was determined to be 6:1 and was proceeded to the KS F 4935 evaluation method. The 2 component type adhesive sealant uses a static mixer and a cartridge type container for the injection procedure and was able to satisfy the evaluation criteria outlined in the KS F 4935 standard.

본 연구에서는 지하 콘크리트 구조물에 누수 발생 시 콘크리트 배면에 주입하여 보수를 시행하는 1액형 점착 실링재에 대해 알아보고 새로운 콘크리트 배면 주입재인 2액형 점착 실링재에 대한 평가를 진행하였다. 2액형 점착 실링재는 아스팔트 계열의 주제와 라텍스 계열의 증점제로 구성된 실링재이며, 주제와 증점제의 배합비에 따라 실링재의 점도편차가 크게 나타났다. 이에 주제와 증점제의 배합비를 투수시험을 통해 확인한 결과 주입성, 경제성, 성능을 고려하여 적정배합비를 6:1로 정하고 KS F 4935 평가를 진행하였다. 2액형 점착 실링재는 static mixer를 활용한 카트리지 타입의 용기를 이용하여 주입이 가능하고 KS F 4935 시험방법에 따라 평가를 진행한 결과 KS 기준을 만족하였다.
