were interground with clinker and gypsum in a laboratory ball mill to compare the power consumption with ordinary Portland cement (OPC) (95% clinker and 5% gypsum). The ternary blended cement took less time to reach the same fineness level as OPC due to soft pozzolana and high grade lime stone, indi-
Obsidian was crushed by using a jaw crusher at laboratory first and then ground by using a ball mill. Table 1 lists the cement fineness. Obsidian was ground in 45, 60, and 75 minutes and fly ash and slag in 20 and 40 minutes to obtain the targeted pozzolan fineness levels within the scope of the study. 2.3.

Industrial closed-circuit tube (or ball) mill schematically presented in Figure 1 was used for cement production. The clinker initially passes through a double-deck screen, where all particles larger than 10 mm are sent to a precrusher. A measured fresh feed mixture (B0) of precrushed clinker, gypsum, and pozzolan is introduced in the mill.

The clinker is then cooled and ground to a fine powder in a tube or ball mill. A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker. Gypsum is added during the grinding process to provide means for controlling the setting of the cement.
Cement pastes prepared at w/c=0.4 with white portland cement (WPC) and a 90:10 blend of white portland cement and VCAS pozzolan GP6 gave TB-1C values of 62.3 and 70.1, respectively. Thus, the VCAS pozzolans have a color/brightness that is somewhat whiter and brighter than white portland cement itself.
