Abstract

The purpose of this study is to develop a fluidity-improved refilling material that satisfies smooth construction and long-term durability in a low-temperature environment using special materials and field soil as a refilling material to develop technology for high-speed installation of long-term non-traditional pipelines on poor ground containing a large amount of organic soil in a low-temperature environment. To this end, a special cement material was developed, and an indoor test was conducted to determine the construction performance and durability of the fluidity improved refilling material mixed with the developed special material and field soil to meet the quality standards for field construction. The construction quality standard items of fluidity improved refill materials were set to meet the CLSM (ACI 229R-13) standard suggested by the American ACI (America Concrete Institute). In addition, in order to understand the applicability in a low-temperature environment, the test was performed with the same items at low temperature and compared with the indoor test results at room temperature.

본 연구에서는 저온환경의 유기질토가 다량 함유된 불량한 지반에서 장기적으로 안정적인 비전통유 파이프라인 고속설치 시공을 위한 기술을 개발하기 위하여 되메움 재료로써 특수재료와 현장토를 사용한 저온 환경에서 원활한 시공성과 장기 내구성을 만족하는 유동성 개량 되메움재를 개발하는 것이 목적이다. 이를 위하여 시멘트계 특수재료를 개발하였으며 개발된 특수재료와 현장토를 혼합한 유동성 개량 되메움재의 현장시공 품질 기준에 만족하기 위한 시공성과 내구성을 파악하기 위한 실내시험을 수행하였다. 유동성 개량 되메움재의 시공품질기준 항목은 미국 ACI(America Concrete Institute)에서 제시한 CLSM(ACI 229R-13) 기준을 만족하는 것으로 목표를 설정하였다. 또한, 저온환경에서의 적용성을 파악하기 위하여 저온에서 동일한 항목으로 시험하고 상온의 실내시험결과와 비교평가 하였다.
