Blast Furnace Slag 미분말을 혼입한 순환골재고강도콘크리트의 역학적 특성에 관한 연구

초록

With the increasing construction of high-aspect-ratio structures in the 21st century, demand for high-strength concrete has grown substantially. At the same time, public concern over the environmental impact of construction materials and waste is intensifying. This study addresses these concerns by exploring two approaches: expanding the use of recycled concrete aggregates and utilizing blast furnace slag as a cementitious material. Recycled aggregates are generally believed to reduce the strength of high-strength concrete; therefore, this work evaluates their feasibility in high-rise applications by varying mix proportions and ratios. Furthermore, the potential of blast furnace slag to partially replace cement is examined for its practicality and long-term benefits. The objective is to determine the effectiveness of low-cost, sustainable materials in producing concrete that satisfies all performance requirements for high-rise construction while reducing the environmental footprint of concrete production.
