  • Displays, saves and prints
  • PT100 probe measuring range -40 to +300°C
General description

The Heat of Hydration Apparatus is used to determine the heat of hydration of low heat cement as expressed in calories per gram. When Portland or hydraulic cement is mixed with water, heat is generated as a result of the exothermic reaction. The heat generated by cement’s hydration raises the temperature of concrete and this temperature rise causes expansion while concrete is hardening.

The apparatus consists of a Dewar flask housed in an insulated box, an electric stirrer, a filler funnel and a high resolution thermometer.
