A DAMAGE MODEL FOR SULFATE ATTACK OF CEMENT MORTARS

In this presentation, a model for portland cement mortars under sulfate attack from environmental actions is proposed based on a progressive fracturing concept. A damage variable is defined as a function of gel space ratio of mortar. 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.
