Abstract
The data allowing to reveal the most effective solutions for the production of new by-products in the complex processing of nepheline have been obtained. It is shown that calcium hydrocarbon aluminates synthesized under conditions of alumina production play the main role in the technology of new materials: carbon sulfoaluminate-type mineralizers, rapid hardening cements of the "Rapid" type, high alumina cements, foundry cements. The main technical characteristics of new pro-ducts are given.
