This Paper investigates the impact of partial substitution of cement with nonmaterial's (Nanoclay, Graphene Nanoplatelets, Carbon Nano fibres ) on the compressive strength, water absorption and Durability of cement paste against acidic and alkaline attacks. Cement paste mixtures with various replacement ratios (i) 1%, 1.5%, 2% ,3% and 4% of Nanoclay (ii) 0.5%, 1%, 1.5% and 2% of Graphenenanoplatelets (iii) 0.25%, 0.5%, 0.75% and 1% of carbon nanofibres (iv) combination of two nonmaterial's i.e.(0.1%nanoclay+0.1% Graphenenanoplatelets) and (0.1%nanoclay+0.1%carbon nanofibre), were prepared and tested according to the standards. The results show that adding small quantities of nanomaterials could improve the mechanical strengths of cement paste. From the compressive strength test, the results show that the optimum amount of nanoclay, graphenenanoplatelets and carbon nanofibres are 3%, 1.5% and 0.75% respectively. The compressive strength, water absorption and durability against acidic and alkaline media are also studied.
