    Abstract

    A model for cement mortars under sulfate attack is proposed based on a progressive fracturing concept. An initial damage of mortar is defined as a function of the Powers' gel space ratio. The sulfate attack evidenced by the expansion of the matrix is incorporated as additional nucleated voids which increase the initial damage existing before the loading. The compressive properties of cement mortars under sulfate attack are predicted well by this model. Expansion limits for sulfate attack computed by this model agree well with those proposed by Mather and Patzias.
