Chemistry Scientists replaced 40 percent of cement with rice husk cinder, limestone crushing waste, and silica sand, giving concrete a rubber-like quality, six to nine times more crack-resistant than regular concrete. It self-seals, replaces cement with plentiful waste products, and should be cheaper to use.

In Southern Canada we get tempretures that swing between -40c in the winter and +40c in the summer. Concrete on structures is constantly being touched up and any roads made of it are often in pretty rough shape. Most of them are asphalt.
