Abstract :A thermoset PMS insert ignore into journalissuearticles values(Polyvinyl modified silicone); type polymer additive effect on load bearing capacities of cement grouted rock bolt specimens exposed to thermal cycles was investigated with a series of experimental studies. The additive used in this study was in liquid phase while adding into the fresh cement mix and started to solidify by polymerization after being mixed well in the cement grout. The silicone based thermoset product was selected to use because of its ability of polymerization in contact with water. According to the results of this study, the load bearing capacity loss due to thermal cycles was found to be notably limited as a result of using the thermoset additive. Therefore, the additive tested in this study was assessed to improve resistivities of the cement grouted rock bolts against the thermal changes.
