The use of ultra alkaline aluminosilicate rocks of Buryatia in construction materials technology

The article presents the results of studies on the use of ultra-alkaline aluminosilicate rock of Buryatia - synnyrite for the production of binders and concretes. It shows some characteristics of natural raw materials and the main directions of their use. It is proved both theoretically and experimentally that use of synnyrite in combination with carbonate rocks leads to obtain additives that can be used as hardening accelerators of different binders; and as a component of active fine ground composite binders in combination with alkali salts as the hardening intensifier of Portland cement. The use of fine ground original rock in the presence of potassium carbonate allows to replace up to 30% of cement without changing the compressive strength of cement.
