“The olive oil production process was based on two major steps. The first step involved crushing the olives using a crushing stone and then collecting them into a basket. The second step is done on another installation: the basket is pressed with force, extracting the oil out of the crushed olives and collecting the juice into a storing vat.

Chemical Reactions in Pozzolanic Concrete
After quarrying the rock is crushed in different stages. The first crushing reduces the rock to a maximum size of about 15cm and the secondary crusher or hammer mills reduces the rock size to about 7.5cm or smaller. A mixture of crushed rock and other ingredients such as iron ore or fly ash and ground, is fed to a cement kiln.
