to batch and load any quantity of any mix design on demand. Centralized batching can scale quickly with less movement than on site mixers, using aggregate trucks, cement tankers and ground stocks to achieve up to 240 cubic metres an hour from a single plant. This allows consistent large-scale pours across a site quickly, as supply logistics for cement, water, and aggregate are fixed to a single point with greater storage capacity, and therefore easier to scale, and more tolerant of short supply interruptions. For small loads (orders under 10 yards) transit mixers typically return to their batch plant after each delivery. Volumetric trucks can go directly from job to job until a truck is emptied, reducing traffic and fuel consumption.
