EINPHASIGES HYDRAULISCHES BINDEMITTEL, HERSTELLUNGSVERFAHREN UND DAMIT HERGESTELLTER BAUSTOFF
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 no more 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 0.75 to 2.75, and the binder containing 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 converting calcium-containing and silicate-containing starting materials into a preproduct which at least in part contains a calcium hydroxosilicate, subsequent grinding of the calcium hydroxosilicate until the monophase hydraulic binder forms, 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.
