I heard back from the person who posted on this fascinating concept over in a Non Traditional Housing discussion thread on Tribe. S/he writes:
"Well, the glass/cement info was in one of many engineering texts I checked out from my university library a couple of years ago. I can't recall which book it was now, but I was thinking of running some of my own experiments eventually anyway so I'll just do it sooner and send you the pictures and data.... the basic idea was to simply replace gravel and sand with similarly-sized particles of glass, with mixture ratios being about the same as usual, I think. I'll test Portland cement with various glass colors and mixtures and report back. It may take a month or so. I also recall seeing interesting data on cement/perlite mixtures (the "popcorn-like" air-filled rock pebbles common in commercial potting soil) that where much lighter and better insulators than regular concrete, just not as strong."
Whenever the results of that experiment are in I'll let 'yal know, and will pass Carey's note about glass aggregate (Glasscrete) along back to Robbie.
Does anyone know if it is part of this glasscrete wall technique to take an industrial polisher to the inside and outside surfaces after the pour is set? From working with industrial application dalle de verre stained glass panel walls I know that the more polished the surface of the glass on the outside of the wall where sunlight strikes, the more sunlight which enters and is passed inside via the glass. Likewise, the more polished the surface of the glass on the side of the wall facing into the room, the brighter the residual sunlight shining through. Seems like grinding and polishing the inside and outside surfaces of a glasscrete wall could significantly raise the luminosity of the glow coming through, if technically feasible and cost-effective.

Astonishing skill! This archer is a real-life Legolas and then some!
