초록

This study investigated the application of red muds, which were industrial wastes fired at 800℃, with a coloring agents. The results were summarized as following. The slumpflow, air content and unit weight volume were satisfied with each target values. The setting time was shortened on the case that 3 % of the red coloring agent and fired red mud were simultaneously replaced about 1 hour compared with the previous study which was 6 % of the red coloring agent was individually used. For the length change ratio caused by drying shrinkage and depth of neutralization on hardened concrete, they were declined when 3 % of the red coloring agent and fired red mud were simultaneously replaced compared with the previous study. On the measurement of forming colors, the case that 3 % of the red coloring agent and fired red mud were simultaneously replaced was similar to the previous study.
