Abstract
The effect of curing temperature on the strength development of the SDF material is discussed in this paper. Experimental results show no "cross-over" effect over the one year curing period. An Arrhenius equation based maturity model is used to analyze the experimental results, from which the apparent activation energy is determined and the value shows good agreement with reported values in literatures. The model prediction also shows reasonable agreement with the experimentally determined strength-strength correlations between the accelerated and normal curing conditions.
