POLYMER MODIFIED CONCRETE. CREEP STUDIES OF POLYESTER POLYMER CONCRETE UNDER FLEXURAL LOADING

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 deg C, time periods up to 160 hours, and stress levels from 4 to 12 MN/m sq which represent stress-to-strength ratios of 0.3 to 0.7. The data obtained over these ranges of temperautre, stress and resin content were successfully superposed on a single master curve of creep compliance versus time. On the basis of these results a single expression is proposed, which describes the creep compliance of the PC system as a proudct of separable functions of temperature, stress, resin content, and time.
