Water uses in cement plant

Process and storm water at concrete plants is referred to as water from concrete production operations in ASTM C1602. Process water is also generated when returned concrete is washed out in concrete reclaimer systems. These systems collect process water with the cement and aggregate fines in the form of a slurry that can be re-used

    The strength of the paste depends on the ratio between water and cement – the weight of the mixing water divided by the weight of the cement. High-quality concrete is produced by lowering the water-cement ratio as much as possible without sacrificing its workability. Almost all natural water can be used for mixing concrete
