Effect of Temperature on the Rate of Setting of Gypsum

EXPERIMENTS carried out in this laboratory with some commercial gypsum plasters show that, between 0 and 50 C., temperature may exert a comparatively small effect upon the rate of hydration of ...

Effect of high temperatures on gypsum based composites

Effects of the addition of glass fibres, mica and vermiculite on the mechanical properties of a gypsum-based composite at room temperature and during a fire test Article Feb 2014

Pharmacological properties of traditional medicines. XXV

Effects of ephedrine, amygdalin, glycyrrhizin, gypsum and their combinations on body temperature and body fluid Biol Pharm Bull . 1999 Feb;22(2):165-71. doi: 10.1248/bpb.22.165.

Physical and Mechanical Properties of Gypsum Like Rock

Although many scholars have carried out a series of research and discussion on the physical and mechanical properties of gypsum rock, the use of A-class α-high-strength gypsum powder to pour remolded samples, and four groups of natural, 45 C dehydrated, water saturated, and 220 C high-temperature dehydrated samples were processed in the ...

Research on the Effects of Calcination Temperature on the

This paper studies the different calcination temperature on the properties of titanium gypsum physical effects, and the mechanism of the effects are discussed in this paper. Research has shown that with the increase of calcination temperature, the mechanical properties of titanium gypsum present a trend of after rising first down. When the calcination temperature is 180 C, titanium gypsum ...

Effect of citric acid on setting inhibition and mechanical

The paper assesses the influence of the calcination temperature of synthetic gypsum binder 14 on the binding properties of innovative gypsum pastes, as well as on masonry and plastering mortars.

Effect of Temperature on the Structure of Set Gypsum

VARIATIONS within the normal range of temperature do not exert a very profound effect upon the rate of hydration of gypsum plaster1,2. For example, Fig. 1 shows the maximum rate of increase of ...
