The results of research and development of mineral-alkali (geopolymer) binders on the basis of waste production and processing of magmatic rocks are presented in the article. The influence of the type of magmatic rock, hardening conditions, modifier admixture and content of the activator were investigated. The influence of composition complex activator on the basis of sodium silicate on the properties of binder was found. It is shown that mineral-alkali binder on basis of crushed magmatic rocks can be obtained by resource-and energy saving technology. To obtain binder with strength of 60 ... 70 MPa and high water resistance and low absorption of water in its composition should include 25% of blast furnace slag by weight of the binder and complex activator on basis of sodium silicate in amount of 7 ... 9% and 2 ... 2,5% of sodium hydroxide.
