    Admixtures are used in concrete (often in combination) to impart specific qualities to the fresh or hardened concrete. Some admixtures make the concrete set faster or slower, or make it denser, or make it stronger or more durable. The most common are water-reducing admixtures. They help produce a medium slump, workable
