Investigation on phosphogypsum–steel slag–granulated blast-furnace slag
The SSC of 85% slag, 10% phosphoanhydrite and 5% clinker was found to have the highest strength values at 90 days. Singh and Garg [6] investigated a durable binder based on calcined phosphogypsum, fly–ash/granulated blast-furnace slag and portland cement. The gypsum binder was found suitable for use in masonry mortars, …
