This research is to reduce the formwork leakage of high-fluidity concrete caused by insufficientaccuracy of formwork fabrication widely used for high-fluidity concrete to general strength concrete. However, in the actual construction site, because of the insufficient accuracy of formwork fabricationmay cause leaking concrete of mortar through a gab of the formwork. Therefore, in this research, whichbuilds on previous research into providing thixotropy with PVA and Borax, the use of thixotropy toreduce high-fluidity mortar leakage was evaluated. The results of the experiment proved that the useof thixotropy with PVA and Borax can contribute to reduction of the formwork leakage of high-fluiditymortar. This finding is expected to lead to further research on reducing leakage of high-fluidityconcrete. |
