Single-phase hydraulic binder, methods for the production thereof and structural material produced therewith

Abstract

The invention relates to a monophase hydraulic binder containing silicon, calcium, oxygen and hydrogen atoms in an arrangement comprising silicate building units having an average connectedness of higher than Q1.5 and silanol groups, with none or a part of the calcium atoms being substituted for by a metal atom M[6]x+ sixfold or higher-coordinated with oxygen and/or none or a part of the silicon atoms being substituted for by a metal atom M[4]y+ tetrahedrally coordinated with oxygen, the molar ratio of [CaO+(x/2)·(M[6]x+Ox/2)]: [SiO2+M[4]y+Oy/2] having a value of 0.2 to 2.0, and the binder having an H2O content of 3.5% by weight to 20% by weight, as well as a mixture containing this binder. Furthermore, the invention relates to methods for manufacturing the binder or a mixture containing this binder by reaction grinding a starting material of silicate building units having a connectedness of Q0 to Q2, and optionally further materials, with a solid silicate raw material having a ceonnectedness of the silicate building units of Q3 to Q4 and optionally drying the monophase hydraulic binder to an H2O content of 3.5% by weight to 20% by weight. Finally, the invention relates to a building material made by setting the binder or a mixture containing this binder with water and subsequent hardening.
