| Abstract |
This study deals with the properties of PMMA mortars using Expanded Polystyrene(EPS) solution-based binders. An unsaturated polyester(UP) resin is used as an effective crosslinking agent. PMMA mortars are prepared with various UP resin contents of the binder, and tested for working life, exothorm temperature, length change, flexual and compressive strengths, and temperature dependence of flexual and compressive strengths.
As a result, the working life of PMMA mortar is lengthened with raising UP content of binder. Length change of the mortar was condensed from expansion to shrinkage with increasing UP content, and non shrinkage of the mortar is obtained at about UP content of 2.5%. While the flexual strength of the mortar is decreased with an increase in the UP content, the compressive strength of the mortar is increased with an increase in the UP content and reach maximum at UP content of 5%. However, thermal resistance improvement of the mortar by crosslinking reaction of UP resin is not recognized. The use of UP resin as an effective crosslinking agent for shrinkage control of PMMA mortar is recommended |
