摘要

At least one basic concrete mixture consists of cement, sand, water and possibly lower-quality hard stone that is sieved and tamped into a mold. A facing layer of concrete is placed on top of the basic concrete mixture, combined and compacted. The facing layer consists of a concrete basic mixture and a number of additives, which harmonize with the color. The compacted concrete layer's surface is then dry-brushed.
