CONCRETE & CEMENT HISTORY
Oldest surviving concrete is found in Yugoslavia which was thought to be laid in 5600 BC.
The first major users were Egyptians around 2500 BC and Romans from 300 BC.
Romans mixed materials from “Pozzuoli” a pink sand with lime mortar and built their structures. This is nothing but volcanic ash and they produced the first “POZZOLANIC” Cement.
