Concrete!

You might think that concrete is a modern building material, but would it surprise you to learn that the Romans used a form of concrete, in fact, we are still debating how precisely it was made. The most likely ingredients are lime, seawater, and volcanic ash!
The ancient Romans used concrete to build iconic structures such as the Roman Pantheon. Today the largest concentrate structure is the Grand Coulee Dam in the United States, it contains nearly 12 million cubic yards of concrete, for comparison, modern housing uses an average of 66.5 cubic yards.
The recovery of the housing market and the government’s drive to ‘Build, Build, Build’ our way out of a recession will see concrete in more demand than ever!
Unfortunately, concrete as a material isn’t great for the environment, which has led the construction industry to look for alternatives. Introducing Green Concrete:
“Green concrete is a form of eco-friendly concrete that is manufactured using waste or residual materials from different industries and requires less amount of energy for production.”
Do you think the construction industry has a duty to look for sustainable resources?
