- Synopsis
- This report introduces concrete using ground granulated blast furnace slag as a substitution material for ordinary Portland cement in replacement ratios ranging between 10% and 70%. Based on laboratory experiments, this report explains the effects of the type, quality, and replacement ratio of ground granulated blast furnace slag on various properties of concrete, and based on on-site practical experiments, it describes the production and workability of the resulting concrete and the strength development characteristics of mock-up members made using such concrete. From these results, the mix design of concrete using ground granulated blast furnace slag and its carbon dioxide reduction effect were considered. In recent years, various ecological concretes have been developed and put to practical use to reduce the environmental impact of concrete. From this viewpoint, this report also aims at the dissemination of widely applicable ecological concrete, such as the simplification of production and management.
