Experimental Test On Carbon Nano Powder On The Properties Of Concrete

ABSTRACT Cement concrete is one of the most versatile building materials ever created. More and more often, microfibers and polymer or carbon nano fibers are added to concrete mix, causing beneficial changes in material properties. Nanotechnology, has only recently found its way into practical building applications and building materials, including concrete. The outstanding mechanical properties of Carbon nano powder have generated great interest for their potential as reinforcements in high performance cementitious composites. The main challenge in research is the proper dispersion of carbon nano powder in the cement matrix. The results revealed that inclusion of Carbon nano powder in the design mix improves both the tensile fracture characteristics and compressive strength when not mixed with a surfactant compound. The improvement in the mechanical properties specimens with the addition of nano powder are observed more clearly with increasing curing age. The mixing process to achieve uniformly dispersed and properly mixed mortar however requires specialized equipment, such as ultrasonic mixers. It is assumed that carbon nano powder are distributed uniformly in the cement and there is perfect bonding in the interface of cement and nano powder. In our Project We Are Choosing M20 Grade of Concrete and addition of 3g carbon nano powder with weight of cement
