Abstract
In this Application Study based on the result of the Basic Study, the field test was performed to compare the quality of Ready-mixed shotcrete with that of the existing field mix shotcrete, and the long-term durability was evaluated as tunnel supporting. The plant manufacturing system was also designed to produce standardization materials, and the prototype products were produced with that system. The All-in-one silo mixer was designed and the field construction system using the All-in-one silo mixer was proposed to be most effectively applied Ready-mixed Shotcrete in construction fields. And the application of Ready-mixed Shotcrete was confirmed that more superior to the field mix Shotcrete by evaluating the Constructability and Economics.
레디믹스트 숏크리트의 적용성 평가에서는 기초 연구 결과를 바탕으로 현장실험을 통해 기존 현장배합 방식과의 품질 비교를 수행하였고, 지보재로서 장기적인 내구성 평가를 실시하였다. 그리고 규격화된 재료 생산을 위한 공장생산 시스템을 도출하고 시제품 생산도 실시하였다. 실제 시공현장에서 가장 효과적인 적용을 위해 일체형 사일로 믹서 설계 및 반영된 현장시공 시스템을 제안하였다. 또한, 시공성 및 경제성 평가를 통해 기존 현장배합 방식보다 우수한 적용 가능성을 확인하였다.
