I'll be a little less specific than the previous answer. A concrete batch plant needs aggregate, cement, sand, water, possibly fly ash and other admixtures.
Water Content and Concrete Mix Ratio . The more water that is added to a concrete mix, the more fluid and workable the concrete becomes. However, this comes with a price of strength. More water equals weaker concrete. The water-cement ratio is important for the concrete to reach its design strength.
