In the 21st century, demand for high strength concrete is increasing due to the trend toward construction of maximum vertical aspect ratio structures. Concurrent with this is the increasing societal emphasis on the environmental effects of construction materials and construction waste. Given the need for increasingly high strength concrete, this study examines two potential solutions to the correlative environmental issues. First is the potential for generalized use of increased amounts of recycled concrete aggregate. Second is the potential for utilization (and thus recycling) of blast furnace slag as cement. Typically, the use of recycled aggregate has been thought to reduce the strength of high strength concrete. In this study we will examine variations in the mixture ratios and in the percentage of recycled aggregate concrete to determine whether, and in what ways, it is of practical use in high rise construction. This study will also examine the practicality and long term effects of using blast furnace slag as cement materials.
Through this study we hope to evaluate the effectiveness of these elements in producing concrete which meets all requirements of high rise construction, while utilizing lower cost materials which at the same time reduce the environmental impact of concrete construction.
