26. Concrete in its raw essence is a very green material. It is hewn from rock and the earth, ground into a fine powder, mixed with a few other raw components, the most important is water, and then mixed and allowed to set, wherever it is needed. In its raw state concrete powder is environmentally friendly, as it is of the environment itself – a natural component.
