Abstract: This study investigates the feasibility of using GNP (Graphite nanoplatelets) as a novel conductive admixture for developing multifunctional cementitious composites, aiming at enhancing their mechanical properties, electrical properties, and making them sensible to their internal damage. After the addition of GNP, up to 20% and 17% increases were observed in compressive strength and flexural strength of mortar, and an increase of up to 82% was observed in flexural strength for cement paste. Mortar added with 5% (by weight of cement and sand) GNP showed significant increase in conductivity. Besides, it obtained the self damage sensing ability by showing electrical resistance increase when internal damage occurs. This study serves as a preliminary development for smart construction materials that can monitor the integrity of the structures. Further researches are needed before the results in this study can be applied to real structures.
