Via wet grinding process, high reactivity of GGBS would be obtained and the strength of mortars could reach 27 MPa at the age of 28 d [48]. Furthermore, the dissolution of ions in waste gypsum could be also expedited by wet grinding. It was expected that wet grinding would significantly promote the hydration of gypsum …

Fig 4 shows material flows during the cement grinding. Clinker, gypsum, and additives are matched in required proportions by a weigh feeder, after which they are conveyed to the mill that performs the remaining grinding. The grinding process occurs in a closed system with an air separator that divides the cement particles according to size.

Gypsum (C 0 G 100) is the softest material among the studied; however, it has a sharp feed PSD and low size, which can increase the resistance to grinding. This is seen by gypsum's initial fineness (n = 1.42), which has a narrower PSD than limestone (n = 0.70). The uniformities of the materials were very similar after being ground by the ball ...
