This study conducted an experiment to verify the flexural reinforcement effect based on the state of damage by reinforcing damaged reinforced concrete slabs with composite mortar, in order to ascertain the effect of reinforcement construction methods verified to improve the strength of the structure and noise between floors on actual buildings. The method of experiment was conducted based on the “2017 Safety Inspection and Precise Safety Diagnosis Guidelines” of the Korea Infrastructure Safety and Technology Corporation, and the damage on the actual specimen was determination based on the displacement value occurring on the specimen. The experiment of introducing damage was set to a scope that can be reinforced to a state before the reinforced bar yielded, and only the damage of composite mortar was induced to conduct the experiment. The method of damaging the composite mortar was examined by comparing the values of the concrete material experiment result and the values of the composite mortar induced by an existing equation. The principal variables of the bend experiment included the wire mesh diameter, use of POSS, and damage levels 1, 2 and 3, and a total of 10 specimens were produced.
