·The precursor to concrete was invented in about 1300 BC when Middle Eastern builders found that when they coated the outsides of their pounded clay fortresses and home walls with a thin damp coating of burned limestone it reacted chemically with gases in the air to form a hard protective surface Rome By 600 BC the Greeks had

·The Invention of Roman Concrete A Historical Overview Roman concrete known as opus caementicium was developed in the 3rd century BCE Unlike modern concrete which uses Portland cement as a binder Roman concrete was made from a mixture of lime mortar volcanic ash known as pozzolana and water This blend was
·Why was the invention of concrete important Roman concrete is significantly more impenetrable to erosion by seawater than modern concrete By using pyroclastic materials that react with seawater starts to form Al tobermorite crystals over time The widespread use of concrete in many Roman structures ensured that many
In fact the Latin name for Roman concrete is opus caementicium after caementa — rough unhewn quarry stones that reminded the Romans of the fist sized pieces of rock that were used for aggregate Aggregate could be composed of natural materials but builders waste was the most common source Mortar was created by mixing lime water and
Examples of concrete made with this cement still exist in structures such as the Pantheon and Colosseum in Rome The birth of modern concrete as we know it today can be attributed to a stonemason from Leeds called Joseph Aspdin He made a new improved cement in 1824 by heating chalk and clay together then grinding it down to fine powder
