Claim 0:
1. A method for the kinetic regulation of cementitious binders and/or cementitious binder compositions, the method comprising
1) providing a cementitious binder,
2) providing at least one borate mineral,
3) mixing the cementitious binder and the at least one borate mineral in any given order, and
4) optionally admixing an activator selected from the group consisting of CaO, Ca(OH)2, CaSO4,and combinations thereof,
the method further comprising 5) grinding the at least one borate mineral,
wherein a dosage and/or a specific surface area of every borate mineral is chosen in a way that a product P as defined by the equation P=D·(SSA)1/2,
wherein D is the dosage of the respective borate mineral in weight % relative to the cementitious binder and SSA is the specific surface area of the respective borate mineral in m2/g,
is from 0.01-75.
