SINGLE-PHASE HYDRAULIC BINDER, METHODS FOR THE PRODUCTION THEREOF AND BUILDING MATERIAL PRODUCED THEREWITH |
摘要 |
The invention relates to a monophase amorphous hydraulic binder containing silicon, calcium and oxygen atoms in an arrangement comprising silicate building units having an average connectedness of at least Q1, 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 no more than 45 atomic percent 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 1.5, and the binder having less than 3.5% by weight of water, 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 containing silicate building units having a connectedness of Q0 to Q2, with a solid silicate raw material having a connectedness of the silicate building units of Q3 to Q4 and optionally drying the monophase hydraulic binder to a water content of below 3.5% 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. |
