MORTARS FOR THE ENHANCEMENT OF THE INDOOR ENVIRONMENTAL QUALITY
Keywords:
mortar, colloidal silver nanoparticles, mechanical properties, antibacterial activityAbstract
Achieving a healthy indoor environment is an important concern in the construction and building materials industry. This study fits in the context of these concerns and demonstrates the possibility of developing mortars that contain colloidal silver nanoparticles with good antibacterial properties. The optimal recipe was established by replacing 50% of the amount of water in the mortar recipe with a commercial 25 mg/L colloidal silver solution. The obtained mortars have superior physical and mechanical characteristics and excellent antibacterial properties against various Gram-positive and Gram-negative bacteria, compared to standard mortar.
