Concrete Washout and Flocculants

Concrete producers have problems with wash-out water containing high concentrations of solids. Historically, settling ponds have had to be rather lengthy in order to allow enough settling time to effectively separate the suspended solids from the water. SlurrySep™ solves this problem by accelerating the settling through flocculation. Color pigment may also coagulate and settle rapidly. If

Treating Concrete Wash Water AWE International

03/04/2015· Concrete wash water typically has a pH of between 11 and 13.6 (depending on the degree of dilution) due to the presence of dissolved lime (calcium hydroxide) and other hydroxides released as the cementitious material hydrates. Similarly, slightly less alkaline waters (typically pH 10 to 12) are generated by hydro-demolition works and rainfall either running off freshly poured concrete slabs or

THE EFFECT OF WASTE WASH WATER ON THE CONCRETE

The disposal of leftover concrete and waste wash water from ready-mix concrete trucks is becoming an increasingly greater environmental concern. When an empty 9m3 ready-mix truck returns to the batch plant from the construction site, there is still approximately 200 to 400 kg of concrete adhering to the inside of the drum and mixing blades. It takes approximately 700 to 1300 L of water to wash
