Ancient Egypt - Moulded concrete - what if this is true?
okay, so it's a really irritating editorial style... but, what if the ancient egyptians knew how to make CONCRETE from crushed rose granite and other pummelled stone?
This same 'concrete technology' has been witnessed all over the ancient world i.e. South America, also.
ADDITIONAL RESEARCH: here's some extra testimony from Professor Joseph Davidovits, who's been cracking on about (agglomerated) limestone and marble and granite i.e. CONCRETE, since 1979.
Levelling off a site is also easier with CONCRETE... you don't need spirit levels and technology of any sort... you just make a pit and pour in the mixture, and the mixture will AUTO-LEVEL.
