Abstract

In this study, the purpose of this study was to quantitatively grasp the specific correlation between the raw material and the occurrence of leakage by analyzing the characteristics of leakage by adjusting the type and content of the raw material constituting the asphalt mastic coating waterproofing material. To this end, two raw materials, CA (calcium carbonate) and ASE (anti-sedimentation), which are organic and mineral extender for asphalt mastic waterproofing membrane coating, were selected. viscosity and oil leakage stability (20 ℃, 40 ℃) was evaluated. As a result of the evaluation, the oil leakage stability and viscosity were inversely proportional to the CA average particle size, and it was quantitatively proven that a correlation in proportion to the ASE content was established. The results of this study are expected to be used as core data for basic mixing design in the future mixing studies to improve leakage of asphalt mastic waterproofing membrane coating.

본 연구에서는 아스팔트 매스틱 도막방수재를 구성하는 원료의 종류 및 함량을 조정하여 누유발생 특성을 분석함으로써 원료와 누유발생 간 특정 상관관계를 정량적으로 파악하는 것을 목적으로 하였다. 이를 위해 아스팔트 매스틱 도막방수재의 유·무기계 체질안료인 CA(탄산칼슘)와 ASE(침강방지제) 두 개 원료를 선정하였으며, 입도 및 함량을 변수로 설정하여 배합을 통해 샘플시료를 조성하고 샘플시료별 점도 및 누유안정성(20℃, 40℃) 평가를 진행하였다. 평가결과, 누유안정성 및 점도는 CA 평균입도에 반비례하며, ASE 함량에 비례하는 상관관계가 성립하는 것을 정량적으로 증명하였다. 본 연구결과는 향후 아스팔트 매스틱 도막 방수재의 누유 개선을 위한 배합 연구 시 기초 배합설계의 핵심적인 근거자료로서 활용이 가능할 것으로 판단된다.
