摘要：

The effect of anhydrous cement on the thermal stability of vinyl-type polymer concretes has been studied by investigating the interaction between the polymers and the calcium compounds of cement. It was proven from differential scanning calorimetry that C2S and C3S have a significant effect on the thermal stability of polymethyl methacrylate and polystyrene. From infrared analysis, the reaction mechanism appears to occur between the calcium oxide in the filler and the -CH2- groups in the polymer. Polymer concrete containing 17 wt% C2S maintained excellent strength after exposure for 30 days to 25% brine solutions and to air at 238°C. © 1979.
