What is light emitting concrete and the purpose to provide that concrete?

Light-emitting concrete involves the use of optical fibers within the concrete to form a mixture that emits light from the brighter side of the wall to the darker side.

It is made up of concrete with relatively finer materials. Fine aggregates are actually quite fine, and the Nominal mean size of coarse aggregates isn’t exceeded 10 or 12 mm. 4% optical fibers are added in suck a way to create a kind of mesh with the fibers continuing from one face to the other, this carrying light from one facet of the other. The optical fibers very interestingly, act as the reinforcement in concrete and no steel is required.

The reduction in compressive strength is negligible, and hence, it is quite the architect’s favorite concrete.
