Abstract
A method for the kinetic regulation of cementitious binders and/or cementitious binder compositions, the method including the steps of providing a cementitious binder, admixing at least one borate mineral to said cementitious binder, and optionally admixing an activator selected from the group consisting of CaO, Ca(OH)2, and/or CaSO4.
Claims10
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.
