Abstract:

Repair is termed as “to replace or correct deteriorated, damaged or faulty materials, components or elements of a structure” Mortar is considered a mix of cement, sand, and water; in few cases, additives such as chemical admixtures may also be used. The application of mortars is primarily in masonry, plaster, and repair works. Special Repair Mortars are engineered material, or one can say readymade mortar with constituents proportioned in a manner to obtain desired physical and chemical properties. Special repair mortars may be utilized in spalling of concrete, repair of concrete surfaces due to honeycomb cum segregation, concrete affected by the ingress of aggressive substances, and rehabilitation of stone masonry dams and other site-specific requirements. The paper envisages the experimental investigation on the physical properties of special repair mortar and detailed application procedure adopted in the rehabilitation process of one of the stone masonry dams.
