Stabilization and solidification of sewage sludges with Portland cement

Valls, S. / Vazquez, E.

The objective of this work is to create a binding and stabilizing matrix with sludge-cement and sludge-cement-coal fly ash. With this purpose, studies have been made on the effects of various percentages of waste and binder and the behaviour and evolution of sludge in the system of cement and cement-coal fly ash pastes. In these studies, evaluations were made on the setting speed, the hydration products formed and the chemical stability by means of the pH values attained and of the types and concentrations of microorganisms and organic compounds in the system created.
