Thanks, this is very helpful. So here's another bullet for your
list- it seems as if fly ash + lime = cement. This would mean that
those of us in wettish climates who are concerned about maintaining
maximum vapor permeability in lime plasters would be best off
avoiding fly ash as a pozzolanic additive. Yes? And what about
ground pottery or bricks (which I have used alot of) or hydraulic
lime? Do these have a similar effect on the lime? My understanding
is that they produce different compounds, entirely.
And you might be interested to hear that Amy (my wife) regularly
refers to pozzolanic additives as pozzolanic adjectives, because she
is finds them very exciting. It has something to do with being
allowed to build up such modified plasters as thickly as she might
