<HTML>Sandy,
So, if I read this correctly...
1. The geopolymer doesn't 'ooze' down because it is too firm at the time of packing... so even if a one or two inch crack DID exist under it, it wouldn't glop down to fill that space.
2. The seperate and distinct block construction model was chosen to make it 'earthquake proof'... in other words, the seperation of blocks give the structure some "wiggle room".
3. The gypsum mortar has been chemically shown to be different from standard gypsum mortar used at other sites. This gypsum has a limestone element in it. I will assume that this is NOT limestone mortar, as we know that takes an excessively high temperature to make... but a geopolymer mortar, combining the burned gypsum with the limestone geopolymer compound. This mortar, with a greater elasticity, also adds to the "wiggle room" without sacrificing weatherproofing. (so to speak).
Do I understand your answers correctly?
