It is easy to overlook the use of concrete in society. Concrete plays a vital part in our daily lives and in a functioning society. Its benefits to society are immense, being used to build our schools, hospitals, apartment blocks, bridges, tunnels, dams, sewerage systems, pavements, runways, roads and more.
Few people realize that concrete is in fact the most used man-made material in the world, with nearly three tons used annually for each man, woman and child. Twice as much concrete is used around the world than the total of all other building materials, including wood, steel, plastic and aluminium. None of these other materials can replace concrete in terms of effectiveness, price and performance for most purposes.
Even fewer people are aware of the many environmental benefits that using concrete brings.
It is vitally important to develop products and systems that can be used to construct more durable, energy-efficient eco-buildings, and concrete can be used to do just this. Concrete, with its strength, durability and excellent thermal mass, should be a key component in eco-buildings of today and the future.
The environmental benefits of concrete, among others, are:
Strength and Durability
Relatively low emissions of CO
Energy efficiency in production
Excellent thermal mass
Locally produced and used
