Joseph Davidovits explains the chemistry behind this and much more in his books and other works over many decades. Once ridiculed, acceptance of his ideas has slowly grown. Certainly the chemistry that he describes is very repeatable, and the Pantheon and other Roman works are very … can't resist … concrete examples and proof of his ideas. Follow the links in this wiki article and do some Google searches. I read the book in 2000, and was very impressed by the time I finished it. I later met with Davidovitz, and found him to be quite reasonable, intelligent and clear thinking. The biggest obstacle was/is that it was in more people's interest to promote the "mystery of the pyramids", and established dogma in academic circles than to just repeat his experiments. http://en.wikipedia.org/wiki/Joseph_Davidovits http://en.wikipedia.org/wiki/Joseph_Davidovits
