| Popis: | Curing temperature is one of the primary factors determining geopolymeric reactions. A total of 66 cylindrical specimens, subjected to 11 different curing regimes over 24 h, were tested for compressive strengths at 1, 28, and 90 days after curing. The test results demonstrated that coupled effects exist between the maximum temperature, its duration, and the subsequent residual temperature. A model based on the weighted maturity concept was developed to predict compressive strength, reflecting the coupled effects of temperature and duration. The developed model was shown to be superior to other models based on the maturity or rate constant concepts. |
