you make it by mixing limestone powder and clay in a kiln
limestone is used to make cement
Limestone is made up of calcium oxide which is the key ingredient to make cement. The limestone is mixed in with a particular clay to get the cement mixture.
The materials used to make cement are,Calcareous materials (limestone)Argillaceous materials (clay)gypsumCoal dustIron oxidemagnesiumAlkalies
Cement is hydrated limestone. Concrete is cement, stone and sand. Sometimes fiberglass fibers are added to increase strength.
they used limestone blocks only but they are so heavy and big they stayed put
Cement
clay + limestone = cement

Limestone is refined to make portland cement.
calcium carbonate (limestone)
it is mixed with clay to form cement.
cement is formed from limestone by combustion of limestone ( heating of the limestone)!
Limestone is the sedimentary rock that is used to make cement. Some limestone is made of old coral reefs that have been buried by deposits.
Cement water =concrete. Clay limestone= cement shells stone =limestone plankton+stone =shells
Limestone has greater strength and better bonding capacity.Limestome is crushed in to fine particles in the preparation of cementLimestone is the major constituent in cement of about 60-67%.
It makes glass!!
