Concrete may generally be a good choice for sidewalks, but it is a brittle material – this means that it needs to be poured thick, in order to keep those sidewalks from cracking under pressure. Scientists from Singapore's Nanyang Technological University, however, are developing an alternative. They've created bendable concrete that they say could be easily applied in the form of relatively thin, light paving slabs.
Ordinarily, concrete is made from a mix of cement, gravel, sand and water. The new material, known as ConFlexPave, additionally contains polymer microfibers. These are thinner than the width of a human hair, and serve to distribute loads evenly across the entire slab, instead of keeping them focused in one location.
