Scientists from the Center for Military Research of the Far Eastern Federal University (Russia) have developed a unique concrete, which is a mixture of cement and a binder (up to 40% of the total mass), consisting of rice husk ash, limestone crushing waste and quartz sand.
As a result of using such a combination, concrete becomes, as it were, "rubbery" - it compresses and bounces under mechanical stress, without cracking. In this respect, its capabilities are nine times higher than those of conventional concrete. In addition, it self-compacts when poured, which makes it indispensable for the construction of underground structures and bunkers.
Another advantage of the new material is that in its creation, in fact, industrial waste is used, which makes it cheaper. According to the head of the project, Professor Roman Fedyuk, the next goal of the researchers will be to obtain concrete that is resistant to radiation.
