THERE'S PLENTY OF ROOM AT THE BOTTOM, OR HOW NANOTECHNOLOGIES CAN CHANGE THE WORLD OF CONCRETE Part 2

It's quite impossible to imagine modern construction without concrete. Today the world volume of concrete being produced is more than 4 milliard of m(3) per year. Concrete is used under different operational conditions, it is ecologically friendly material and it has unlimited source of raw materials and comparatively low cost. One should also mention its high architectural and construction expression, comparative simplicity and accessibility of technology, opportunity to use widely local raw materials and anthropogenic wastes utilization in its production, low energy intensity, ecological safety and operational reliability. Undoubtedly it is the reason why concrete will remain the main building material in the foreseeable future.
