Technology of production of dry building mixtures is of great importance in the promotion of domestic and foreign market of construction materials. Currently, the dry mixtures are of great importance in the decoration of buildings and premises. It is noted that the basis to meet the new needs of builders is the production of dry building mixtures. Dry mixes have recently become to be used as thermal insulation materials, improving the efficiency of construction. This article discusses the use of dry construction mixtures with quartz cements with various chemical additives. It is noted that the advantage of production technologies of dry mixtures is the possibility of individual and, where necessary, repeated modification of their components, chemical additives or mechanical treatment, with obtaining materials of wide application. Of hydrophilic additives C-3 and LSTM-2 from the position of «filler» effect to all the particles of dry mix is preferred LSTM-2, and guarantees a longer preservation in time. Metal quartz powder industrial waste, introduced into the Portland cement or the dry mixture, pushing the grain and contribute to a more complete hydration of the cement. Quartz cements are advised to prepare for low-frequency shock-attrition modes of external influence, and dry mixes on their basis of high-frequency turbulent regimes with an air pressure of 6 atmospheres.


Dry mixes modified with additives, chemical additives, mortar mixes, concrete mixtures, quartzbearing cements.
