Abstract

An inorganic binder and mortar was developed for ground reinforcement based on industrial by-products, and its applicability was evaluated through laboratory and field experiments. Laboratory mixing tests were conducted on the mortar containing 70% industrial by-products as the inorganic binder and circulating fluidized bed boiler bottom ash as an aggregate substitute. An optimal mixing design method according to field conditions and required strength levels was investigated and its applicability was evaluated through the field experiment. The proposed foundation method using industrial by-product-based mortar can install uniform columns by pre-boring and then injecting the high-strength mortar based on industrial by-products. Therefore, it is expected to be effectively utilized in applications such as structural foundations, embankment piles, and embankment reinforcement.

본 연구에서는 산업부산물 기반 무기결합재와 지반보강용 모르타르를 개발하였으며, 실내 및 현장 실험을 통해 그 활용성을 검토하였다. 산업부산물을 70% 적용한 무기결합재와 골재 대체재료로 순환유동층보일러 바텀애시를 혼합한 모르타르에 대해 실내 배합시험을 수행하여, 현장 여건 및 요구강도수준에 따른 적정 배합설계 방안을 제시하였으며, 현장 시험시공을 통해 현장 적용성을 확인하였다. 본 연구에서 제시한 산업부산물 기반 모르타르를 적용한 기초공법은 선천공 실시 후 산업부산물 기반의 고강도 모르타르를 주입하여 균일한 단면의 개량체를 형성할 수 있어, 중저층 구조물기초, 성토지지말뚝, 하천제방 보강 등에 효과적으로 활용될 수 있을 것으로 기대된다.
