Abstract:

In recent years, polymethyl methacrylate polymer concrete (PMMA-PC) has been used extensively in the field of construction works. It is needed because it will harden within 1 hr at low temperatures. A basic investigation of the low-temperature curing characteristics of workable PMMA-PC is the focus of this paper. PMMA-PC and its binder are prepared with various binder formulations, and the working life of the binder and the peak exotherm time and compressive strength of PMMA-PC are examined under various low-temperature conditions. The working life of the binder and the peak exotherm time of PMMA-PC decrease with an increase in promoter and cross-linking agent contents and a rise in test temperature. The contents of the binder with the desired working life at low temperatures less than 0ousC can be estimated by using a nomograph prepared in this investigation. The peak exotherm time of PMMA-PC can be predicted from the working life of the binder. In conclusion, the optimum binder formulations are recommended for the low-temperature applications of PMMA-PC, which hardens and develops a high compressive strength of about 500 kg/cm2 in the range of 0ousC to -20ousC within approximately 1 hr.
