Description
Summary:The present study reported the mechanical behaviour of reduced Graphene Oxide infused in cement mortar. In this investigation initially well graded Graphene Oxide confirming the presence of carbon functional group by FTIR Spectro results it is dispersed in suitable dispersion agent to obtain reduced Graphene Oxide [rGO]. The reduced Graphene Oxide was ultrasonicated with different hours of sonication at 1, 2, 4 and 6hours to reduce the oxygen functional groups. A series of cement mortar composite with varying percentages of reduced Graphene Oxide were prepared to achieve maximum strength by examining the compressive strength for different curing periods. The mechanical test results revealed that the composite containing reduced Graphene Oxide with 0.1% dosage showed good dispersion and well compressive strength prepared for 28 days than the plain cement mortar composite with 4hour sonication time. The strength of cement mortar prepared decreased after the time of sonication amplified from 4hours to 6hours due to interfacial bonding between the cement paste decreased. This study delivers a valued influence toward better understanding of the influence of reduced Graphene Oxide particle size on the properties of cementitious composites to optimize their performance.
