- Abstract
Modular construction is a green and low-carbon construction method. In this paper, the effect of expansive agent (EXP), mixed steel fiber (SF) and polyvinyl alcohol fiber (PVA) on the workability of self-compacting concrete (SCC) were studied. The filling performance, passing capacity and anti-segregation performance of SCC with different mix ratios are investigated. It is found that the workability can be improved by adding EXP and reduced by adding hybrid fiber. The formula of the relationship between slump flow and the amount of EXP, SF and PVA is obtained by correlation analysis simultaneously. When the EXP content constitutes 7%-10% of the cementing material, the workability of the freshly mixed SCC is optimized. Additionally, to ensure proper filling performance at an EXP content of 7%, the volume content of total fiber in concrete should not exceed 0.25%. At an EXP content of 10%, this volume content should not exceed 0.29%.
