Chloride Ingress Resistance, Microstructure and Mechanical Properties of Lightweight Mortars with Natural Cork and Expanded Clay Prepared Using Sustainable Blended Cements

The use of lightweight aggregates in construction materials is a good solution for increasing the contribution to sustainability civil engineering works, such as maritime ones. In this regard, possibility using cork granulates and expanded clay current research topic. combination eco-friendly cements with could provide solutions developing new building materials. work, it has been studied mortars prepared sustainable natural clay. These incorporated slag, limestone fly ash. Reference only sand aggregate were also made. total porosity pore size distributions obtained. non-steady-state chloride migration coefficient compressive flexural strengths determined. tests performed at 28 days 1 year. differences between series not high, depending on binder. Natural showed similar or slightly higher coefficients than reference This adequate resistance low mechanical observed recommend possible non-structural cement-based works exposed environments.
