On Pretreatment Experimental Study of High Strength Gypsum by Yunnan Phosphorus Gypsum

Article Preview

Abstract:

This thesis mainly studies the preprocessing of making high strength gypsum powder by using phosphogypsum. And bring out the new preprocessing of phosphogypsum from the traditional methods. And the new method improved the traditional 3 kinds of processing methods. After processing of phosphogypsum, strength and crystal morphology were compared to shown the better one.
