Past earthquakes have shown that conventional masonry buildings are often most vulnerable to damage in case of an earthquake. Several approaches have been deployed in the past to strengthen the masonry structures against extreme loading events. One of the most widely used strengthening mechanism is the application of externally bonded inorganic composite systems on masonry substrate. In recent years, with a focus on environmental conservation and sustainability, there are continuous efforts to use ecofriendly materials and innovative methods in construction instead of conventional materials and methods. Several studies have been conducted in the past to characterize such materials and to determine their suitability for short- and long-term applications.
