"This substitution gives slabs of the concrete a somewhat rubber-like
quality, allowing them to contract and spring back when subjected to
impacts, instead of cracking. In fact, the material is reportedly six to
nine times more crack-resistant than regular concrete. Additionally, it
self-seals upon being poured, meaning that it could be well-suited to
the construction of underground structures such as bunkers.
And as an added bonus, because the new concrete replaces cement with plentiful waste products, it should also be cheaper to use."
I would like to invest please.
