been the case in the
past, and remains true
in our present time.”
One famous American
geologist wrote a paper
in 1992 that states:
“... we feel it is the
duty of a professional geologist to expose
this egregiously absurd
archeological
theory
before it becomes part
of entrenched pseudoscience... We believe
that if Davidovits had
any understanding of
basic geologic principles and understood
the implications of simple geological evidence
at Giza, he would have
realized that this geopolymer theory has no
basis in fact... We have
also shown how geologic common sense can
destroy archaeological quackery, but not,
unfortunately, before it
has enjoyed widespread
publicity among the
gullible and sensationminded... The geopolymer theory is defunct;
we still remain in awe of
the enigma of Egyptian
skill and engineering.”
Ironically, his study was
made on stone samples taken from natural
limestone that was part
of the bed-rock upon
which the pyramid was
constructed.
T.D. There is an increasing trend in science and technology to go f or
greener materials, and geopolymer is certainly an example of a sustainable cement material. But are there any shortcomings? How well does it
perform in comparison to conventional cement materials?
Dr. Davidovits
The only and major
shortcoming is its novelty. It is too young.
Geopolymer
cement
was invented only 30
years ago (Portland
cement, 150 years ago).
Since liability claims for
construction
materials require at least 20
52
years durability warranty, everybody should
understand that, as far
as the applications for
the construction indus-
