Abstract
The paper reports the incorporation of graphene into fly ash cement mortars at different doses (% by weight of cement) and evaluation of compressive and flexural strength and resistance to sulphate attack of composites at different hydration times. Fine recycled aggregates (FRA) from have been used as total replacement of fine natural aggregates (FNA) in mortars. Compressive strength and flexural strength results showed that 0.05% graphene produced maximum increase of 8% and 13% respectively with respect to FNA mortar. Excellent resistance to sulphate attack in 0.05% graphene composite could be achieved with minimum loss in compressive strength of 21%.
