Abstract

A modelling approach is proposed to simulate drying shrinkage and shrinkage- induced microcracking in cement paste. The proposed approach takes into consideration the heterogeneous nature of the cement paste as well as the development of the microstructure due to fast-paced hydration at early-ages. Simulations show that the development of microcracking depends on the initial conditions, the drying depth and the drying threshold age.
