Abstract:This paper describes changes of stress and strain during the setting of prismatic specimens incorporating polymer mortar. A new apparatus measures setting shrinkage stress and strains developed at both ends of polymer mortar specimens while at constant temperature. This apparatus is simple in structure, consisting of a noncontact type displacement device and a load measuring device. The relationships of setting shrinkage stresses and strains, and elastic modulus of three kinds of polymer mortar are reported. Furthermore, the mechanical properties of three kinds of polymer mortar were investigated. Finally, the deflection and strain that occur when polymer mortar is overlaid on ALC (Autoclaved light weight concrete) beams includes both analysis and experimental data on the two layered structure.
