Solid-Phase Modification of Cement Systems by Organosilicon Polymers
In this paper, studies of solid-phase modification of cement systems with organosilicon polymers are presented. Modification of organosilicon polymers was carried out by co-milling clinker and polymers. The number of polymers directly related to cement particles and the features of their adsorption are studied. As demonstrated on the basis of studies of IR spectra, polyorganilsilsesquioxanes and polydiorganosiloxanes participated in chemical interaction with cement systems. Structural characteristics of cement systems (specific surface and particle size), formed during mechanochemical modification, are studied. It is shown that the mechanochemical introduction of organosilicon polymers leads to a significant increase (by 30-60%) of the resistance of cement stone to freezing-thawing in salt solutions.
