Concrete fiber microscopy (IMAGE)
Caption
Above is a look at several different types of internal fibers highly magnified through a microscope — including fibrillated basalt fibers tightly bundled together (a), a fiber reinforced polymer, with internal glass fibers glued together with resin (b), the magnified end of a hook steel fiber (c) and a single striated steel fiber (d). These internal fibers are the key to giving ultra-high-performance concrete its strength.
