研究了废渣区风化磷石膏作为波特兰水泥缓凝剂的适用性。以1、3、5、7、10和12.5重量%的比例添加PG对凝固和机械性能的影响对波特兰水泥进行了研究，并与含有天然石膏（NG）的波特兰水泥进行了比较。结果发现，根据土耳其标准，PG可以代替NG用于波特兰水泥。最高的28天的抗压强度被发现在样品与3重量% PG.（C）2004 Elsevier Ltd.保留所有权利。
In this study, usability of weathered phosphogypsum (PG) from residue areas as set retarder in Portland cement was investigated. The effects on the setting and mechanical properties of PG added in ratios 1, 3, 5, 7, 10, and 12.5 wt.% to Portland cements were studied and compared with a Portland cement containing natural gypsum (NG). It was found that PG can be used in place of NG for Portland cement according to Turkish standards. The highest 28-day compressive strength was found in the sample with 3 wt.% PG.
