Civil engineers use steel, fiberglass and other similar materials to increase concrete\u27s strength and toughness, but using those materials often requires costly construction techniques. Short-wire reinforced concrete should become a favorite technology since the process is compatible with standard construction processes and the steel used for the bone-shaped fibers is relatively cheap. Researchers at Department of Energy\u27s Los Alamos National Laboratory have discovered that enlarging the ends of small fibers mixed into concrete substantially increases the material\u27s overall strength and toughness
