CONCRETE CONSTRUCTION

Picture
The history of concrete construction dates back thousands of years, with the earliest evidence of concrete structures found in Syria & Jordan around 6500 BC: 
  • Nabataea traders
    Built concrete floors, housing structures, and underground cisterns. They discovered hydraulic lime, which hardens when it comes into contact with water. 
  • Ancient Egyptians
    Used mud mixed with straw to bind dried bricks, and gypsum and lime mortars in the pyramids. 
  • Ancient Romans
    Used a mixture of volcanic ash, lime, and seawater, known as pozzolana, which hardened underwater. This made it ideal for marine construction, and many Roman structures still stand today, including the Pantheon and the Colosseum. 
  • Joseph Aspdin
    In 1824, he invented Portland Cement by heating chalk and clay together and grinding it into a fine powder. This was the superior cement of its time, and mass production began in 1828. 
  • Brad Bowman
    In the 1950s, he developed the Bomanite process, which allowed for colored, textured, and imprinted architectural concrete paving. ​
  • Thomas Edison
    In 1902, he introduced the first long rotary kiln, which allowed for better temperature control and more efficient mixing of materials.
