The compressive and flexural strength were determined and the strength at 28 days age was higher or equal to the reference for up to 50 vol% marl replacement of cement. The microstructure of the mortars was characterized by SEM after 90 days curing, as well as their capillary suction rate and saturation. Mortars of all compositions were tested for durability starting after 90 days curing with respect to chloride diffusion, expansion caused by sulphate attack (5% Na2SO4) at both +5 C and +20 C, as well as carbonation.
