Recently polymethyl methacrylate concrete (PMMA-REC) has become widely used for the patching work and precast concrete production because of its good workability and high early strength. It is significant to determine the working life of PMMA-REC on the condition comparable to the ambient temperature in the application field. The purpose of this study was to examine the working lives of PMMA-REC and its binder under various temperature conditions. PMMA-REC was prepared with variation of initiator and promoter contents, and the effects of initiator and promoter contents on the working lives of PMMA-REC and its binder were tested under various temperature conditions. In conclusion, the working life of PMMA-REC is possible to be controlled with variation of initiator and promoter contents, and the nomographs for determining the promoter content at each initiator content under various temperature conditions are proposed.
