عنوان انگلیسی Analysis on Effect of Fullerene Soot on the Chemical and Physical Properties of Cement Mixtures
چکیده انگلیسی مقاله The article reports on the relevance and the necessity of the introduction of various additives in the composition of grouting mixtures. The analysis of cement compositions with various modifications of carbon is briefly outlined. A method for obtaining fullerene soot and an analysis of its effect on the chemical and physical properties of grouting compositions made of alumina cement is presented. The physical, mechanical and operational properties of the modified grouting mixture are considered. The optimal content of carbon nanoparticles in the binder is 0.1-0.5% BWOC. The introduction of fullerene soot makes it possible to obtain high mechanical properties of cement stone (an increase in uniaxial compression strength by about 15% and a decrease in porosity by about 20%) in comparison with cement mix without additives. It has been determined that using carbon materials is environmentally friendly. The addition of fullerene soot to cement system does not affect the cement hydration processes, provides micro-reinforcement of the cement stone, and prevents the propagation of cracks in it at the nanoscale.
