  • Cement Chemistry an overview | ScienceDirect Topics

    Cement chemistry is sensitive to the components of the combustion products. Some contain chlorides. Chlorides and other anions hinder the setting of cement and corrode metal rebars used to reinforce cement structures. 2. The carbon content in ash is also a major factor. High-carbon ash hinders setting of cement. In particular, ash produced by low-NO x burners contains a high proportion of

    High water and organic content of sewage sludge constricts its reuse and disposal. It is often necessary to solidify/stabilize the dewatered sludge with solidifying agents before landfill disposal. In this study, the sewage sludge was conditioned with skeleton builders, i.e., fly ash and lime combined with ferric chloride for the purpose of improving the dewatering efficiency.
