Research of the Phase Composition of Cement Stone with Carbon Nanomaterials

The paper presents the results of studies of the phase composition of cement stone when modified by carbon nanomaterials obtained as a co-product in the plasma gasification of coal. Under the action of electric arc plasma from the material of electrodes and coal fed for gasification, carbon nanomaterials are simultaneously produced in one apparatus. The introduction of carbon nanomaterials increases the physical, mechanical and operational properties of cement and concrete by accelerating the processes of Portland cement hydration, improving the microstructure and changing the phase composition of the cement stone. To study the phase composition of the cement stone with carbon nanomaterials, differential thermal analysis and infrared spectroscopy were carried out. The results of differential thermal analysis and infrared spectroscopy of the cement matrix indicate a change in the basicity of the calcium hydrosilicates formed when carbon nanomaterials are introduced.
