A laboratory investigation on silica fume (SF) and metakaolin (MK) concrete found that the computed efficiency factors varied with pozzolan type, replacement level and age. At 28 days, the k values ranged from 1.6 to 2.3 for MK and 2.1 to 3.1 for SF mixtures, while at 180 days, the k values varied from 1.8 to 4.0 for MK and 2.4 to 3.3 for SF mixtures.

Energy efficiency is improved by dewatering the dilute aqueous suspension of hydrated kaolin clay in stages to provide dry pulverized calciner feed. An initial portion of the water in the dispersed aqueous suspension is removed in an electrofilter operated to produce a more concentrated but still fluid dispersed suspension of hydrated kaolin.

Pigment efficiency is determined by the degree to which the pigment particles are spaced out from one another. These BASF kaolin grades have a plate-like morphology, with a median particle size of 400-800 nm. This allows these extender particles to get in between the other pigments, such that they are better spaced from one another.
