Experimental and Analysis of Adding Silicon and Titanium Carbide Nanoparticles to the Cement PasteExperimental and Analysis of Adding Silicon and Titanium Carbide Nanoparticles to the Cement Paste

Abstract

Now days the use of nanoparticles in the construction field will increase. The nanoparticles help to improve the physical and mechanical properties of the concrete. Nano powder can improve the mechanical properties of cement paste due to accelerating the formation of small sized crystals. The study focus on the structural changes of cement paste when adding Sic and Tic nanoparticles as admixtures in different proportion. Scanning Electron Microscopy and energy dispactive spectroscopy have been employed in identifying the structural changes in nanoparticles modified paste. Silicon carbide (SiC), also known as carborundum. It is hard chemical a compound containing silicon and carbon. A semiconductor, it occurs in nature as the extremely rare mineral moissanite. SiC also has a very low coefficient of thermal expansion (4.0 × 10-6/K) and experiences X no phase transitions that would cause discontinuities in thermal expansion. Which accessories the strength of concrete. Titanium carbide, TiC, is an extremely hard (Mohs 9-9.5) refractory ceramic material, similar to tungsten carbide. It has the appearance of black powder with the sodium chloride (face-centered cubic) crystal structure. Its crystals as found in nature range in size from 0.1 to 0.3 m. Titanium carbide is used in preparation of cermets, which are frequently used to machine steel materials at high cutting speed.Increase the strength of cement paste, Enhance the mechanical properties,Enhance the physical properties.
