WebbIt is interesting that, although the kaolin has a much larger ultimate particle size, it is shrinking much more (23% total vs. 14%). This is even more unexpected since, given that it has a lower drying shrinkage, and should be more refractory. Further, the kaolin has a porosityof 0.5% vs. the ball clay's 1.5%. WebbMetakaolin has a smaller particle size (∼1–2 μm) and higher surface area compared with portland cement, but a larger particle size than SF.
