Abstract

Recently, water leak is increasing due to poor compaction or segregation of concrete on external wall. In addition, the flatness quality of the slab is lowered due to the deterioration of the workability of concrete. In this study, the performance of high fluidity concrete of 21MPa using a polycarboxylate-based superplasticizer was evaluated to improve the compaction and quality of the concrete wall.
