Abstract:The creep of unsaturated polyester/styrene polymer concrete (PC) under flexural loads was investigated using two PC systems with different resin contents, as well as the unfilled resin. Measurements were taken at temperatures, ranging from -5 to 60 C, time periods up to 160 hours, and stress levels from 4 to 12 MN/m², which represent stress-to-strength ratios of 0.3 to 0.7. The data obtained over these ranges of temperature, stress, and resin content were successfully superposed on a single master curve of creep compliance versus time. On the basis of these results, the authors propose a single expression that describes the creep compliance of the PC system as a product of separable functions of temperature, stress, resin content, and time
