Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, (water resistant) such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for

In this paper, the batching and delivery of ready-mix concrete are used to illustrate a pull system. Ready-mix concrete is a prototypical example of a batch process, where a customer process (the contractor) releases an order to batch to the supplying process (the batch plant) and receives product as a result (Figure 2).
