[Ferro List] Mearlcell Problems Fixed

[Keith B]

Hi Doug

Interesting report.  When I was experimenting with foamers and foamed 
concrete at bench scale, Mearlcell was very disappointing, perhaps the 
worst performer.  In light of what you say, I now suspect that was 
primarily an artifact of bench scale and the technique I used.  It's 
always well, if uncomfortable, to be reminded that scale and details may 
be critical - and almost infinitely variable with few combinations good 
ones...
