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.

Is it still true we can’t replicate Roman concrete? We studied this in one of my art history courses, how Roman mosaics have stood the test of time, some still standing even today and how it’s a lost art to modern artists. I read that we’ve lost a lot of modern mosaics to time because the binding agents aren’t nearly as good.
