Effect of Activated Sludge on Limestone Reactivity

Abstract— A lot of work has been done on the enhancement of lime reactivity by materials containing alumina silicates through pozzolanic reaction. This has lead to investigation of new sources CaO of alumina silicates. Waste Activated Sludge (W.A.S) was found to be enhancing limestone reactivity but to a certain optimum amount, after which it becomes detrimental. Shrinking Core Model (SCM) with …
