Keywords:
Calcium Aluminate Cements,Phosphates,Concentrated Effluent,Carbonated Slurry,Iron co-precipitated slurry
Incorporation of simulated aqueous secondary wastes in CAC and CAP cements was studied.
Larger reduction in water content in CAP cements cured at 90 C was observed, regardless the type of slurry incorporated.
Formation of Friedels salt in CAC cements and Chlorapatite in CAP cements is identified.
