Abstract

This study was proceeded to analyze thixotropy of cement paste according to the addition timing of PVA and borax as a basic study of thixotropy of concrete. According to experiment results, the case added borax first and PVA later is that cement paste shows low thixotorpy, and the case added PVA first and borax later is that cement paste shows thixotropy but in certain mix condition fluidity of decrease due to a chemical bond between PVA and borax. The case add PVA and borax simultaneously is that cement paste was expressed thixotropy in all mix condition. Therefore the case add PVA and borax simultaneously is suitable for expressing thixotropy of cement paste.
