The effect of graphene nanoplatelet addition on the mechanical, durability and self-healing properties of engineered cementitious composites

Nanomaterial usage is an effective method to enhance the mechanical and durability properties of cementitious materials. Graphene Nanoplatelets (GNPs) are cost-efficient graphene-based nanomaterials that can exhibit graphene-like features. Although GNPs have been found improve properties, their effect on self-healing behavior materials, particularly Engineered Cementitious Composites (ECC), has not examined in literature studies. Therefore, this study aims investigate effects GNP addition mechanical, ECC. During study, durability, characteristics ECC with without were observed by using various non-destructive test methods. Compression test, four-point bending resonance frequency ultrasonic pulse velocity sorptivity electrical impedance microscopic inspection conducted. According results, 0.05% increased compressive strength specimens. With GNP, first cracking strength, ultimate flexural deformation values both for virgin preloaded The specimens performed similarly under bending. cracks either closed completely or extensively compared control crack numbers after failure also greater than Accordingly, improved addition. improvement was evident nondestructive tests. A considerable increment occurred resistance
