Concrete with Improved Impact Endurance for Defense Structures Developed at FEFU

Engineers from the Military Studies Center at Far Eastern Federal University (MSC FEFU) developed a brand-new concrete with improved impact endurance and up to 40% made of waste:

rice husk cinder, limestone crushing waste, and siliceous sand. The new concrete is 6-9 times more crackle resistant than the types produced under GOST standards. The related article was published in Inorganic Materials: Applied Research.

The new concrete is suitable for the construction of military and civil defense structures, load-carrying structures of nuclear power plants, or for buildings in the Arctic.The endurance of the new type of concrete grows with the increase of impact affecting it. A concrete slab exhibits the so-called ‘rubber effect’:

it contracts and becomes springy, but doesn’t crack. According to the engineers, the construction absorbs impact due to its dynamic viscosity. This effect is caused by the reinforcement of concrete, in this case adding metal or touchstone fibers to it.

Impact-proof concrete can resist not only shell hits, but also tsunami waves. Moreover, it has seismic stability. During the pouring the concrete self-seals, which means it can be used to create complex structures including underground constructions.
