Ready-mix concrete manufacturers batch and mix cement, sand, aggregate, water, and additives at a plant, then load the mixed concrete into rotating-drum mixer trucks for delivery to construction sites. The product must typically be placed within a limited time window after mixing, so operations involve continuous truck dispatch, on-site batching equipment, and significant vehicle activity around the plant and on public roads.
