- Abstract
- High fluidity concrete is the concrete that has a high level of fluidity without the separation of materials while it is not hardened and has the self-compacting property without the extra work for compaction. In order to expand the usability of such high fluidity concrete for general usage, the formulation of an economical binder through the recycling of resources and reasonable mixing conditions for normal strength and high fluidity concrete are required. Therefore, this study formulated concrete binders at Level Six using ground granulated blast furnace slag for W/B 0.45 and 0.55, and then, performed a fluidity securing experiment according to the addition rates of a air entraining and high-range waterreducing agent. Accordingly, for the mixes in which the separation of materials occurred, the fluidity securing experiment was run after adding a viscosity agent in the concrete, which was 0.05% of the amount of the powder. According to these results, the optimal mixing ratios regarding the mixing of normal strength and high fluidity concrete using ground granulated blast furnace slag were BFS 15% and a air entraining and high-range waterreducing agent 1.25% for W/B 0.45, and were BFS 30% and a air entraining and high-range waterreducing agent 0.75% for W/B 0.55.
