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.
Claims15
A method for the kinetic regulation of cementitious binders and/or cementitious binder compositions, the method comprising the steps of
- 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, and/or CaSO4,
- the method wherein the dosage and/or the specific surface area of every borate mineral is chosen in a way that the product P as defined by the equation P=D·(SSA)1/2,
- wherein D is the dosage of the respective borate mineral in w % 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.
4 more elements
A cementitious binder composition comprising
- 1) not more than 99.99 w %, of a cementitious binder,
- 2) at least one borate mineral,
- wherein the at least one borate mineral does not form part of the clinker and wherein the dosage and/or the specific surface area of every borate mineral is chosen in a way that the product P of the dosage and the square root of the specific surface area of the respective borate mineral is from 0.01-75.
