  • Dual role of gypsum: Set retarder and strength accelerator

    gypsum regulates the heat of hydration as also the ettringite formation for progressive chemistry. In the anxiety of not to retard cement if the gypsum is reduced below the threshold level, heat of hydration is commensurately profuse leading to internal thermal stresses and incohesiveness. This is where the role of gypsum is evident as retarder.

  • Utilization of weathered phosphogypsum as set

    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).

    1. Introduction. The setting behaviour of cement is mainly due to the reaction of tricalcium aluminate (C 3 A), 3CaO · Al 2 O 3.The reaction of pure C 3 A with water leads to immediate stiffening of the paste, known as flash set. Thus, gypsum is added to the cement clinker during the grinding of Portland cement to retard the rapid reaction between C 3 A and water (Neville, 2002).
