While dust is the principal waste of cement and aggregate production, wastes derived from concrete batching include mixer washout, sludge and returned excess of fresh concrete (Gursel et al., 2014). On average, the amount of waste generated by the ready-mix concrete sector is up to 0.45% of the total production, with a maximum of about 5%–9% in times of great demand ( WBCSD/CSI, 2009 ).

Fine Points of Mixing - Penn State College of Engineering

Concrete can arrive on your job site in two ways, either centrally mixed or truck mixed. While the former is mixed completely in a stationary mixer and then transferred to another piece of equipment for delivery, the latter is a process by which previously proportioned concrete materials from a batch plant are charged into a ready-mix truck for mixing and delivery to the construction site.
