A concrete batch plant requires the use of aggregate, cement, sand, water, and possibly fly ash and other admixtures. Large piles of aggregate and sand will be required depending on the size of the project. This necessitates a large amount of land. There must also be space for a loader to transport this material to the conveyor belts, which are also required.
