RECYCLING PHOSPHORUS SLAG AS A PRECURSOR FOR ALKALI-ACTIVATED BINDER; IMPACT OF TYPE AND DOSAGE OF ACTIVATOR

The objectives of this study were to investigate the suitability of phosphorus slag as a precursor for alkali-activated binder by studying the effects of type and dosage of alkaline activators on compressive strength and efflorescence formation of the material. Different alkaline activators includin...

Description
Summary:The objectives of this study were to investigate the suitability of phosphorus slag as a precursor for alkali-activated binder by studying the effects of type and dosage of alkaline activators on compressive strength and efflorescence formation of the material. Different alkaline activators including; potassium hydroxide, sodium hydroxide, sodium carbonate, calcium hydroxide, and their combinations with liquid sodium silicate were used. Different levels of total alkali content (1, 3, 5 and 7 % by weight of binder) at different silica moduli (Ms = SiO2
