Interactions between admixtures in wallboard production
Wallboard production uses a great number of admixtures to control the technological parameters within narrow acceptance bands. The most important admixtures, which are always used in all production plants, are the liquefier and the foaming agent. These two admixtures interact with each other and with all other admixtures.
Water-reducing Refinforcing Admixture for gypsum
After mixing type WRA-I Water-reducing Reinforcing Additive into the gypsum, compared with mixing traditional melamine type Water-reducing Additive, the viscosity of gypsum slurry is smaller, solid content is higher, and it is more better for construction, keeping-water and fluidity.

Retarding Admixture - an overview | ScienceDirect Topics
Retarding admixtures (retarders) are known to delay hydration of cement without affecting the long-term mechanical properties. They are used in concrete to offset the effect of high temperatures, which decrease setting times, or to avoid complications when unavoidable delays between mixing and placing occur.
Study of Effect of Chemical Activators and Mineral Admixtures ...
A kind of FGD gypsum from Ningbo Beilun Power Plant of China and fly ash were used as the raw materials with which a complex cementing material was made. Effect of the related factors such as water proportion, mineral admixtures and chemical activators on characteristics of Hemi-hydrate FGD gypsum-fly ash complex cementing material is studied through a number of single factor experiments.
Seven Must-Use Concrete Admixtures (Additives)
Admixtures are added to concrete batch immediately before or during mixing concrete. Concrete admixtures can improve concrete quality, manageability, acceleration, or retardation of setting time, among other properties that could be altered to get specific results.
