cement slurry can be pumped. This state of affairs continues for most of the induction period. But when hydration picks up after the induction period, the cement grains begin to link together and the slurry is not pumpable. Compressive strength deve ops as the hydration products become inter- grown. The reactions speed up as tempera- ture increases. Reaction speed also depends on the rela
