Tóm tắt

The model for drying creep from Part III is here extended for the temperature effect. The basic, additive form of the double power law and the shrinkage-like term are preserved, but certain coefficients become temperature-dependent to reflect the acceleration of drying and of aging. Satisfactory agreement with test data is achieved.
