Abstract

In this paper, a conceptual model for analyzing the plastic part of autogenous deformation of cement paste based on the Arrhenius rate theory will be presented. The autogenous deformation will be calculated from the elastic deformations with inclusion of creep. Different kinds of cement paste with a water cement ratio 0.3 are tested and studied, and experimental result compare the model calculation. The results lead to the conclusion that early age creep plays a very important role in the autogenous deformation of hydrating cement paste and should not be neglected in simulation models.
