Russia develops more resistant cracked concrete.

Researchers at the Military Research Center at Russia's Far Eastern Federal University have recently developed a concrete material that is more resistant to cracking than conventional concrete.
cement is usually cement as a bond, and in this study, about 40% of cement was replaced by a adhesive containing rice shells, limestone debris, silica sand, etc.
the new concrete is 6 to 9 times more resistant to cracking than traditional building materials, and the concrete is suitable for military facilities, urban defense structure, nuclear power plant load-bearing structure and

. It is also suitable for construction structures in extremely cold areas such as the Arctic Circle.
the strength of this concrete also shows a rubber effect that has a lot to do with the impact resistance of building materials, when the concrete is hit, it shrinks and has a certain elasticity, rather than cracking. It is precisely because of the dynamic viscosity characteristics of the concrete that it is able to absorb shock energy.
"We have conducted precise formulation studies on the specific components of concrete materials to improve the cracking resistance of concrete, because once the concrete cracks, corrosion problems ensue," said Professor Roman Fediuk of the Center for Military Studies at the Russian Far Eastern Federal University. Today, the world is committed to counter-terrorism security, protective facilities should be able to withstand artillery attacks or aircraft impact. From our point of view, we are working on impact-resistant materials, and the next step is to develop radiation-resistant concrete materials. "
