Masonry construction is themost widely used buildingmethod in the world. Concretemasonry is relatively low in cost due to the vast\navailability of aggregates used within the production process. These aggregatematerials are not always reliable for structural use. One\nof the principal issues associated with masonry is the brittleness of the unit. When subject to seismic loads, the brittleness of the\nmasonry magnifies. In regions with high seismic activity and unspecified building codes or standards, masonry housing has\ndeveloped into a death trap for countless individuals. A common approach concerning the issue associated with the brittle\ncharacteristic ofmasonry is addition of steel reinforcement. However, this can be expensive, highly dependent on skillfulness of labor,\nand particularly dependent on the quality of available steel. A proposed solution presented in this investigation consists of introducing\nsteel fibers to the lightweight aggregate concrete masonry mix. Previous investigations in the field of lightweight aggregate\nfiber-reinforced concrete have shown an increase in flexural strength, toughness, and ductility. The outcome of this research project\nprovides invaluable data for the production of a ductile masonry unit capable of withstanding seismic loads for prolonged periods
