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.
Gypsum Matrix International. Gypsum uses include: manufacture of wallboard, cement, plaster of Paris, soil conditioning, a hardening retarder in Portland cement.
Cement retarders control the time when a slurry will set hard, keeping the slurry viscous and pumpable in expected wellbore temperatures and for the amount of time required to place the slurry. Retarders decrease the rate of cement hydration, acting in a manner opposite to that of accelerators. COMPONENT R™ Retarder. A retarder enhancer, when combined with a primary cement retarder,
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).
Gypsum Retarder does not contain any materials that interfere with Portland cement or Calcium Aluminate cements. It can be used in blends of gypsum with these types of cements to prevent the early stiffening caused by gypsum. Recommended for industrial use only. PACKAGING . Item #99419: 44-lb (20-kg) bag.

The aim of this research is to study the technical feasibility for the use of FGD gypsum in partial or total substitution of natural gypsum as retarder additive of the Portland cement. Three stages were considered to achieve this goal. Firstly, it was carried out the characterization and comparison of FGD gypsum with natural gypsum. Secondly, based on analysis of results of the first stage

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).

23/05/2020· Gypsum cement is different than gypsum plaster, or plaster of Paris, which possesses neither the high quality of the cement nor its unique characteristics. Gypsum cement is much harder and more reliable than plaster of Paris, and some brands are infused with special agents that can make the material fire retardant or lower the level of moisture absorption.
