(PDF) Production of Cement | Engr Sajid Chaudhary

Cement was later reinvented by the Greeks and the Babylonians who made their mortar out of lime. Later, the Romans produced cement from pozzolan, an ash found in all of the volcanic areas of Italy, by mixing the ash with lime. Cement is a fine grayish powder which, when mixed with water, forms a thick paste.
