Abstract
The yield value of unsaturated polyester resin mortar is not clearly observed and the viscosity of resin varies depending upon the change of temperature and the mix proportions of diluent. Therefore, it is difficult to decide the mix proportions of the resin mortar according to the same design procedure as that of cement mortar.
In order to make clear the relation between the mix proportions of resin mortar and its workability, viscosity, flow, and segregation tests were carried out. From these test results, the workability of the resin mortar was found to be estimated by the viscosity of resin and resin paste.
Based on the results, the mix design of the resin mortar with a constant viscosity is proposed in this paper.
