Costing of Production and Delivery of Ready Mix Concrete - …

Hence, time is critical when it comes to the delivery process of RMC because as time passes, the properties of fresh concrete change quickly, causing it to become unusable within few hours. If the truck travel time exceeds the cold-joint time (the time within which the concrete hardens), the concrete is rendered useless and must be dumped, which raises the operating cost.
