    OverviewProductionEtymologyHistoryCompositionAlternative typesSafetyProperties

    Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. Concrete production is time-sensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens. In modern usage, most concrete production takes place in a large type of industrial facility called a concrete plant, or often a batch plant. In general usage, concrete plants come in two main types, ready mix plants and central mix plants. A re
