Abstract:
Currently, the most active research areas dealing with cement and concrete are understanding of the hydration of cement particle sand the use of nano-size ingredients such as alumina and silica particles. There are also a limited number of investigations dealing with the manufacture of nano-cement. If cement with nano-size particles can be manufactured and processed, it will open up a large number of opportunities in the fields of ceramics, high strength composites and electronic applications. In this paper, the compressive strength with the setting time of concrete by partial replacement of cement by Al2O3 nanoparticles with the average particle size of 80 nm at different curing days (7 days, 28 days, 90 days) were cast and tested has been studied.The results indicate that Al2O3 nanoparticles up to maximum of 2.0% produces concrete with improved compressive strength.
