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 ...
