The Effect of Alkali Silica Gel Formation from Alkali Silica Reaction in Mesoscopic Scale

Tabet, M. / Guettala, Abdelhamid

In this article we treat a pathological problem for a better understanding of the phenomena of ASR; the modeling of ASR has been represented in a relative element of volume (REV) in mesoscopic scale. The method used to estimate the formation of ASG is the kinematic estimation of the ASR where it generates in the end an expansion, thus modeling leads to a better range of understanding of the rheological behavior of a concrete with ASR.The numerical model adopted to validate the effect of the expansion of alkali silica gel in terms of strain/stress is a phenomenological one, where it gives sustainable results with the rheological models.
