Assessing Mortar Mixes for Retrofitting Damaged RC Columns

Columns are essential structural elements that support the weight of a building. If they fail, the entire structure can become unstable. This study examines three different types of mortar to determine which is most effective for reinforcing and repairing damaged columns exposed to uniaxial compression. The research focuses on war-damaged buildings in Benghazi, Libya, aiming to find the best mortar Mix for structural rehabilitation. Each mortar mix was designed to strengthen columns under two stress conditions: one where the load is applied until cracks first appear and another where the load continues until total failure. The study evaluates key factors such as compressive strength and flexibility to determine how well each mortar Mix stabilizes damaged columns and prevents further deterioration.
