Hi Khazar-khum,

For anyone with construction experience in it would be evident that rocks more than 5/8 inch would be an unsuitable as a building material for the ramps, as it would crush into smaller and smaller pieces under the load weights placed on the ramps. I guess to clean up they crushed the gravel from the ramps to use as a building material like the cast limestone blocks that are supposed to comprise the pyramids according to Joseph Davidovits theory. Maybe the houses you are talking about are small cast limestone blocks made from the midden of the ramps? lol

Regards
