On the synthesis of slag-lime binder based on self-loosening blast furnace slag.

As a result of the lead thermodynamic calculations the most probable ways of course of reactions hardening developed in slag-alkaline binding material have been studied. It is established that during hardening insoluble and low-soluble phases — low-basicity hydrosilicates of calcium and analcite are formed. These phases are the most proof to influence of the salts containing in sea water, in comparison with Portland cement minerals. The synthesized slag-alkaline binder can be recommended for application in hydraulic engineering constructions.
