Backfiller Composition With High Flowability
The present invention provides a high-flowing filler composition suitable for backfilling of excavations after a structure is completed in constructing the foundation of buildings, bridges, culverts, drainage pipes, retaining walls, and other structures. A binder composition for a high-flowing filler according to the present invention is usually composed of: 5 to 20 wt% of Portland cement; 75 to 90 wt% of supercritical fluidized bed boiler fly ash; 0.5 to 3 wt% of calcium aluminate; 3 to 8 wt% of petro-coke ash; and 0.1 to 1.0 wt% of a high-performance water reducing agent.
본 발명은 건물, 교량, 암거, 배수관, 옹벽 및 기타 구조물의 기초를 시공하는데 있어서, 구조물이 완성된 후 터파기 자리의 되메우기 공사에 적합한 고유동 채움재 조성물을 제공한다. 본 발명에 따른 고유동 채움재용 결합재 조성물은 보통 포틀랜드시멘트 5~20중량%; 초임계 유동층 보일러 플라이애시 75~90중량%; 칼슘알루미네이트 0.5~3중량%; 페트로코크스애시 3~8중량%; 고성능감수제 0.1~1.0중량%를 포함하여 조성된 것임을 특징으로 한다.
