Patent ID: 8226763

Claim:
A monophase hydraulic binder containing silicon, calcium, oxygen and hydrogen atoms in an arrangement comprising silicate building units having an average connectedness of smaller than or equal to Q 1.5 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+ O x/2 )]:[SiO 2 +M[4] y+ O y/2 ] having a value of 0.75 to 2.75 and the binder containing 3.5% to 20% by weight of H 2 O.
