ABSTRACT
This study examines the effectiveness of adding graphene nanoparticles to plaster mortars, assessing both their mechanical and economic influence. The base materials were characterized, complying with relevant standards, and a Type S standard mortar was designed, which not only met but exceeded the minimum regulatory requirements for strength and adhesion. Experiments were conducted with four concentrations of graphene nanoparticles, comparing them with pre-mixed blends and an in-situ mix. The tests revealed that adding 0.25% graphene significantly optimizes compressive strength and adhesion without compromising workability. Higher concentrations of graphene were found to negatively impact these properties. Cost analysis identified that the mix with 0.25% graphene offers the best cost-benefit ratio for plaster applications.
