How do you make translucent concrete?

To make translucent concrete, you'll need Fiber Optic Plastic (FOP) and ROCALITE microconcrete (www-rocalite.com)

ROCALITE is a very strong mix of concrete in which all the components are micro-metric size and reacts with a very small amount of water, so the paste when wet has is like clay and when sets is stronger than normal concrete. This two factors allows to insert the fibers in the wet mix and keep them in place until the mix sets, about four days later. After that you'll need to polish the surface to let the fibers appears and allow the light passes from one end of the fiber to the other.

The concrete keeps its appearance its strength, is characteristics but the light passes through it

It is amazing
