 This paper examines the flexural behavior of reinforced concrete beams with a smart mortar layer attached to the concrete mixture. The smart mortar layer can detect damage in the beams and infer it through electrical measurements. The research shows that the smart mortar layer can make the beams more sustainable. Additionally, the researchers found that the relationship between the load and the fractional change in electrical resistance is linear. As the load increases, the fractional change in electrical resistance increases. Furthermore, the addition of brass fibers to the mortar-paste increases the fractional change in electrical resistance by up to 18 percent while increasing the ultimate load at failure by up to 8 percent.
