2.2 Cement hydration 2.2.1 Hydration introduction Hydration is responsible for the ‘setting’, which is the sudden loss of plasticity in the cement paste due to its conversion to solid material that occurs prior to the development of compressive strength during the ‘hardening’ (a much slower process) of cement…

Hydration of cement - SlideShare

1.3 Hydration of the cement Chemical reaction of the cement when it is mix with water is called as Hydration of cement. Hydration is the collective term describing the chemical and physical processes that takes place between cement and water. During the hydration process silicates and alluminates are produced and results into the hard mass and this hard mass is called hydrated cement.

Flash Set and False Set| Concrete Construction Magazine

If inadequate amounts of gypsum are added to the cement, flash set can occur--a rapid development of rigidity in freshly mixed portland cement paste, mortar, or concrete. Further mixing can't dispel this rigidity, and a large amount of heat is produced in the process. Rapid development of rigidity can also be caused by false set.

Early Hydration of Portland cement compounds

After the kiln, gypsum is added and it is grinded to finished cement. An overview of the whole process is shown in figure 2. Figure 2 - Cement manufacturing process [2] 3.3 Alite Portland cement contains between 50-70% C 3 S (Ca 3 SiO 5), which makes it the most common component in ordinary Portland cement.

Flash Set vs. False Set| Concrete Construction Magazine

15-02-2001· However, this is not the case for flash set. Flash set is caused by the formation of monosulaluminate or other calcium aluminate hydrates (Ref. 1). It is the rapid beginning of the hydration process and cannot be stopped. Once flash set takes place, there is little anyone can do to stop the hydration process.
