[Catastrophe]

Please show me where the samples are authenticated by a qualified Egyptologist and not illegally 'collected' from a preserved monument.

As I have stated, mortar was used by the AEs and modern repairs have been made. Who collected this sample and from where?

As regards porosity, this is natural:

The two main variants (of limestone) are 1) porous limestone of an inferior quality, which was used mostly in foundations and the core masonry of walls, 2) harder and better quality limestone, mainly used in visible surfaces, casings and similar. The specific gravity of limestone is 1.7 to 2.6 (porous) and 2.65 to 2.85 (dense)

So once again the proponents of mouldy concrete seem to be blurring the 'facts'.

You seem an intelligent person. Can't you see how all the evidence really stacks up?
