Drying Shrinkage Damage in Concrete Repair Systems: A 3D Modelling Study
Differential shrinkage between repair material and concrete substrate is considered to be the main cause of premature failure of repair systems. Magnitude of induced stresses depends on many factors, for example the degree of restraint, moisture gradients caused by curing and drying conditions, type of repair material, etc. Numerical simulations combined with experimental observations can be of great use when determining the influence of these parameters on the performance of a repair system. In this work, a lattice type model is used first to simulate moisture transport inside a repair system and then to model time dependent damage. 3D simulations are performed, and damage patterns and crack widths are qualitatively verified with some experimental observations.
