The physico-chemical methods of the research of hydrated cement by mechanoactivated bonding substance with organo-mineral additive (microsilica + C-3) was presented. It was explored the influence of the additive into the kinetics of formation lowly basic calcium hydrosilicate.
The article deals with the results of theoretical and experimental research on the production of ceramic pigments of blue color with the structure of spinel on the basis of slag of aluminothermal production of ferrotitanium. The sequence of the physical and chemical processes that determine the formation of the set of crystalline phases under drossy pigments burning was established. The influence of the concentration of cobalt oxide and the temperature of researched pigments firing on their optical-color characteristics was studied.
Polyaniline/glauconite-silica (PАn / Gl-Si) composite were obtained by one-step in situ polymerization of aniline in the presence of microdispersion of natural mineral glauconite-silica. The physico-chemical properties (phase content, thermal stability, conductivity and magnetization) of the produced samples of composites with different ratio of components have been studied.
For the first time the series of the composites of aniline and natural mineral glauconite with different ratio of components has been synthesized by oxidation of aniline by ammonium peroxydisulfate in 0.5 M citrate acid aqueous solutions in the presence of dispersion of mineral filler. X-ray phase analysis confirms the amorphous-crystalline structure of produced composites.
