A method of preparing a composition comprising a plurality of first CaO particles and a plurality of first SiO2 particles, wherein the method comprises:
- in a first milling step, milling a plurality of first SiO2 particles in a mill, thereby forming a plurality of first milled SiO2 particles;
- contacting the plurality of first milled SiO2 particles with a plurality of first CaO particles in the mill, thereby forming a mixture of a plurality of remilled SiO2 particles and a plurality of first milled CaO particles;
- and
- in a second milling step, milling the mixture of the plurality of remilled SiO2 particles and the plurality of first milled CaO particles, thereby forming the composition comprising the plurality of first CaO particles and the plurality of first SiO2 particles.
