The aim of the research is to provide thixotropy on cement-based materials. For this purpose, the linkage betweenpolyvinyl alcohol (PVA) and borax was used. Namely, adding the suspensions of PVA and borax in cement paste, thethixotropy of cement paste was confirmed. The thixotropy of cement-based materials can have various advantages onconstruction process, especially, the placing method using pipe can have advantages. As a result of this research, thelinkage between PVA and borax is valid inside of cement paste. Therefore, using PVA and borax, it is confirmed thatthe cement-based materials can have thixotropy with this method, and it can be expected to contribute on developingnew method of placing cement-based materials with thixotropy. |
