Segregation resistance of high fluidity concrete depending on addition method of thixotropy-inducing materials

고유동 콘크리트의 고요변성 부여 물질 혼합방법에 따른 재료분리 방지 여부

The aim of the research is to evaluate the segregation resistivity of the mixture conditions by changing the PVA and borax solutions for thixotropic property on concrete mixture. Since the water addition caused by producing solutions of PVA and borax induces segregation of the concrete mixture, the unit water was reduced by replacing the water amount for PVA and borax solution. By replacing the water from PVA and borax solutions, the segregation was prevented with prefixed concrete mix design and thixotropic properties were also occurred.
