Effect Of Sludge Water From Readymixed Concrete

Reuse of By-Products from Ready-Mixed Concrete Plants for the

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.
