Effect of Free silica/Quartz silica in Kilnfeed - Page 1 of 2 .

If the quartz particle is large enough a wall of C2S forms around the remaining quartz, isolating it from surrounding CaO. ie the reaction SiO2 + 2CaO -> C2S becomes stalled at this point and, no matter how hard the clinker is burned, this free silica can never all react in time. This leaves two equivalents of.
