Concrete consists of a mix of ingredients, including Portland cement, pozzolans, water, coarse aggregates, fine aggregates, and additives. Concrete may also contain mineral colors, granulated blast-furnace slag, and blended cements. When fresh, cement can be molded hours after it is produced. Once the initial set time is reached, the concrete continues to gain strength.
Actually, no concrete can be ordered in many colors. The natural color of concrete is gray because the color of the cement used to make it is typically gray. Take a look at all of the different colors concrete can come in by visiting our Services page.
