The use of nanotechnology is relatively new in civil engineering aspects. carbon nanofibers have unique mechanical properties, and quickly become one of the most promising nanomaterials. Cement and concrete have low tensile strength. The modification of the cement mixture with carbon nanofiber improves the concrete properties, the resistance of water penetration, and also leads to build a better structure. The main objective of this paper is to study the effect of carbon nanofiber on the compressive strength and tensile strength on a mortar mixture. The test on CNF mortar has shown that the addition of such nanofibers decreases the compressive of the mortar by 23.8% and tensile strength of the mortar by 8.65%. The decrease takes place due to the weak adhesion between the particles of cement and nanofiber, and the voids created in the sample by the nanofiber.
