Glass Concrete is a special variation of exposed aggregate concrete. In the case of this concrete, it is the glass particles visible on its surface that result in a particularly appealing appearance. It is especially during daytime that fascinating light effects can be achieved in this manner, giving the concrete a surface of unique vitality in appearance. During the production process of this concrete, glass granules are added in its fresh state, and, after application of a retarding agent, as with exposed aggregate concrete, is washed out or, for example in the case of concrete flooring, can also be polished. As for polished glass concrete, a special glass granule is added to, or spread onto, the fresh concrete. After approximately two weeks, the cured concrete is polished.
