A new form of rubbery concrete that withstands impacts by becoming springy could be used to build defense structures.
The concrete was created by a team from the Far Eastern Federal University, who replaced 40 percent of the cement used as a binder with rice husk cinder, limestone crushing waste and silica sand. This new mixture causes a concrete slab to exhibit a ‘rubber effect,’ contracting and then springing back to resist cracks up to nine times better than standard concrete. The new concrete also makes use of waste products, and so should be more affordable to manufacture.
