3. Results and conclusions
The adsorption complexes with the highest amount of adsorbed CBZ (CL20-CBZ and LDH-DDS- CBZ) are those that showed good biocidal activity, both algaecide and fungicide. After including those complexes in the mortars, it was observed that the material achieved biocidal properties. In the case of the mortars subjected to the leaching test, it was found that the LDH-DDS-CBZ mortar was the one that best retained the fungicide and algaecide properties.
