Comparative study on porosity and permeability of conventional concrete and concrete with variable proportions of natural zeolite additions

With the use of special additives, the concrete benefits over its product life 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 the physica...
