With the use of special additives, the concrete benefits over its productlife increase, both in terms of mechanical properties and durability.Zeolites are used in the field of building work for, thank to their properties,they lend to the concrete enhanced features. This paper explores thephysical and mechanical properties improvements of hardened concreteand its permeability. To this aim, on the one hand a concrete of controland another with Zeolite additions between 5% and 10% have beenmeasured out with respect to the weight of cement, while on the otherCompressive strength and permeability testing have been carried outthrough the Mercury intrusion porosimetry test. After these tests, itwas possible to obtain concrete with Zeolite proportions of 5% and 10%that showed a suitable workability. With respect to the already analyzedmechanical properties, the inclusion of Zeolites as an additive was animprovement. In that respect, the durable features related to this typeof concrete were also similarly improved, being also remarkable the lackof alkali-silica reactions.
