The pyramids of Giza still represent a
mystery, especially the way these pyramids were made. Some
specialists launched the theory according to which the pyramids
were built from some aggregates of granular limestone and some
binder which have at its base alkali of silicate and aluminum.
But there are no strong evidences to sustain this theory. Couple
of samples of Giza limestone was compared with other 6 different
samples of limestone taken from a close area. Micro constituents
with big quantity of silicium mixed with other elements like
magnesium and calcium were discovered in the pyramid samples.
The possible sources of limestone don't have such rations in
their constitution. It is possible that all these elements could
have made a solution together, a thing that nay be proved by the
micro constituents that were found in the pyramid’s vicinity.
More that that the micro constituents found between the
aggregates of natural limestone seemed to be hydrated. One
strange thing is that the micro constituents had remains of
dolomite and calcite that can be hydrated by nature. Some
researches revealed that some of the micro constituents were
nanocrystalline or amorphous that has a quite fast reaction to
precipitations. Other geologists said that the pyramids`
basement is the Mokkatam formation constituted from nummulite
limestone banks that are very tough and huge. The limestone from
the Sphinx vicinity is a nummulite limestone that has a big
quantity of clay. Some recent researches sustained that the Giza
pyramids were made from stone which were brought from quarries
situated close to the pyramids` area, lifted with immense ramps
and placed by a huge number of workers. The researches said that
in the pharaoh times were the necessary materials and skills
to built the pyramids in this way. This theory was also
controversial. |
