Slow exothermic reaction

WebbFigure 12: DSC scan of PET after slow cooling Event 5: Baseline Shift After Endothermic or Exothermic Peaks Causes Baseline shifts are caused by changes in sample weight, … WebbThe chemical reaction between resin and hardener as epoxy cures will generate heat. When this heat cannot escape, it builds up, causing the epoxy to cure faster because epoxy cures faster at higher temperatures. Curing faster because of the heat, the epoxy generates even more heat, even faster.

WebbWith addition of 30% OS, OMEP shows little change, but the growth rate of exothermic rate in the acceleration period slows down and the peak value decreases. This is because the hydration activity of OS is lower than that of cement, and thus almost no slag reaction occurs in the early stage.
