Abstract

Interest in indoor air quality is increasing day by day due to various reasons such as industrial development. Because redmud, an industrial subsidiary, contains titanium dioxide, this study evaluated self-consolidation performance with Slump Flow Test, J-Ring Test, and L-Box Test by mixing redmud in a mixture of ultra-high performance concrete, and sought the optimal combination with high flowability. In addition, the UHPC mixing experiment with photocatalyst was conducted, and the photocatalyst was replaced by the weight ratio of cement and the redmud by the weight ratio of fine aggregate and mixed with the concrete mixture.
