Abstract
The invention relates to a hydraulic binder, comprising K, Ca, aluminosilicates, as well as optionally Li, Na, and Mg, wherein the binder comprises the following components: a) a latently hydraulic aluminosilicate glass with a ratio of (CaO+MgO+Al2O3)/SiO2>1 and b) an alkali activator of the empirical formula (I) a(M2O)*x(SiO2)*y(H2O) (I) wherein M=Li, Na, K, a=0-4, and x=0-5 and y=3-20, wherein the molar ratio of Ca/Si is <1, the molar ratio of Al/Si is <1, and the molar ratio of M/Si is >0.1. Furthermore, it relates to binder matrices, mortars, concrete adhesives, and metal anodes made of such binder.
