Effect of nano-materials on mechanical properties of cement and concrete

Abstract

Cement is as an adhesive that binds pieces of solids together. In this research, the main materials used in construction such as cement, concrete and steel are described. After described that to what extent the nanomaterials of silicon, titanium nanoxide, polypropylene nanofibers, microsilica and nano calcium carbonate do the compressive strength of concrete and cement increase and prevent corrosion and erosion. Polypropylene nano-fibers are added, using titanium nanoxide to increase the compressive strength of concrete. NanoTiO2, NanoAl2O3, NanoFe2O3, NanoFe3O4 and NanoSiO2 have been compared in various studies. It has many effects on compressive strength, erosion resistance and permeability of concrete. This article reviews the research on the use of nanomaterials to improve the compressive strength, erosion and other properties of cement and concrete.
