To improve the mechanical and physical properties of cement by adding the nanoparticles like Sic and Tic. Silicon carbide and titanium carbide powder of 20 nm size is used for the testing. They are adding at different proportion to the cement paste by replacing (1%, 2%, 4%, and 6%). By adding the Nanoparticipates will be increase the physical properties like setting time water absorption. Mechanical properties like compression and flexural strength. Done on 7, 14, 28 days curing.
