Galvanic metal anode embedded in a hydraulic binder comprising a latent-hydraulic alumosilicate glass and an alkaline activator

摘要

The invention relates to a hydraulic binding agent, comprising K, Ca, aluminosilicates and optionally Li, Na, and MG, characterized in that it comprises the following constituents: a) latent hydraulic aluminosilicate glass at a ratio of (CaO+MgO+AI2O3)/SiO2 1 and b) alkali activator of the empirical formula (I): a(M2O) * X(SiO2) * y(H2O), where M = Li, Na, K, a = 0-4 and x = 0-5 and y = 3-20, wherein the mol ratio Ca/Si 1, the mol ratio Al/Si 1, and the mol ratio M/Si 0.1. The invention further relates to binding agent matrixes, to mortar, to concrete adhesive and to metal anodes produced from said binding agent.
