PERFORMANCE EVALUATION OF NANO GRAPHENE IN CEMENT MORTAR
This paper aims to analyse the beneficial use of graphene in cement mortar by comparative study of the mechanical properties of normal strength mortar over the mortar reinforced with graphene. Also the use of construction and demolition waste in different proportions namely 25% and 50% as partial replacement for fine aggregate was made. Graphene was incorporated in the cement mortar of 1:3 grade in the proportion of 0.1%, 0.4%, 0.7% and 1% by weight of cement respectively. The proportion of construction demolition waste and graphene were consequently varied and the corresponding change in mechanical properties, namely, compressive strength, tensile strength and flexural strength of cement mortar was observed at 7th day, 14th day, 21st day and 28th day respectively and the same was compared with the result of normal mortar. It was observed that these mechanical properties increased with increase in the proportion of graphene upto a certain limit after which it decreased. However, the optimum percentage of graphene varied along with the variation in the percentage of C&D waste.
