MONOPHASE HYDRAULIC BINDER, MANUFACTURING METHOD THEREOF AND BUILDING MATERIAL MADE USING THE SAME

摘要

The invention relates to a single-phase amorphous hydraulic binder that contains silicon atoms, calcium atoms and oxygen atoms in an arrangement that comprises silicate-structural units having an average degree of cross-linking of at least Q1. None or one part of the calcium atoms are replaced by a metal atom M[6]x+ that is coordinated at least six-times with oxygen and/or none or at most 45 atom % of the silicon atoms are replaced by a metal atom M[4]y+ that is tetrahedrally coordinated with oxygen. The molar ratio [CaO + (x/2) (M[6]x+Ox/2)] : [SiO2 + M[4]y+Oy/2] has a value of between 0.2 and 1.5 and the binder has less than 3.5% in weight of water. The invention also relates to a mixture containing said binder. The invention further relates to a method for producing said binder or a mixture containing said binder by reaction grinding a starting material that contains silicate structural units having a degree of cross-linking of Q0 to Q2, with a solid silicate raw material having a degree of cross-linking of the silicate structural units of Q3 to Q4 and optionally, drying the single-phase hydraulic binder until a water content of less than 3.5% in weight is reached. The invention also relates to a construction material that is produced by binding the binder or a mixture containing said binder with water and subsequently hardening it.
