Abstract: 
Modeling of ASR requires consideration of numerous parameters to understand the aspects of gel formation, reaction mechanisms and microstructure of concrete. This study attempts to simulate ASR gel expansion and related crack formation in a concrete matrix. Simulation of local expansion of gel is only possible if the mechanical properties of gel are determined. One of the important input parameters in the model, but also one of the key players in the mechanism of ASR, is the amount of expansion of the gel and as a result the internal forces that are generated by this expansion. A small scale testing set up is used to input to a 2D lattice type model. The expansion of gel formed in a single interface is measured. This study includes internal aggregate deformations due to gel propagation together with ITZ elements in a 2D lattice model.
