Ready-Mixed Concrete Plant: Analysis of Sludge Formed

2021-7-23  Ready-Mixed concrete plant operations are large consumers of water. Sludge water is the waste wash water from concrete mixing plants and agitator trucks. Approximately 200 litres of water are used to produce one cubic meter of concrete from a central batch plant. The figure from a truck mix plant

Use of ready-mixed concrete plant sludge water in

2009-4-1  Concrete W prepared with sludge water displayed a shorter time slump loss than the control concrete. This is because sludge water contains absorbent porous sediments that require more water for hydration, resulting in increased slump loss (Chatveera et al., 2006). In the case of concrete mixtures containing fly ash, concrete F mixed with tap water and concretes WF1, WF2, and WF3 mixed with sludge water exhibited a decrease in slump loss compared to the control concrete.

Reuse of By-Products from Ready-Mixed Concrete Plants

for the ready-mixed concrete industry. Sludge water from ready-mixed concrete plants as well as dry sludge, which is derived from the settling of the water, are hazardous for disposal due to their high pH value (pH>11.5). In this work, cement mortars were composed using either sludge water after various treatment, or dry sludge in several ratios.
