In this study, a basic study of thixotropy of concrete was proceeded through cross-linked bond of PVA and Borax. It was noticed that the plasticity viscosity decreased with the addition of Borax, especially the flow tended to decrease at doses from 0 to 50g of aqueous solution at W/C 0.4, and to increase at levels above 50g. |
