In this paper. we consider the mechanical effect of the sulfate attack on concrete. The durability analysis of concrete structures in contact to external sulfate solutions requires the definition of a proper diffusion-reaction model. for the computation of the varying sulfate concentration and of the consequent ettringite formation. https://www.roneverhart.com/SWW-x-SXSW-Cake-Something-Was-Wrong-2-8x3/
