Heat of Hydration

Digital calorimeter 62-L0071/AD
Heat of hydration is the heat generated when water reacts in contact with the cement powder. The amount of heat released depends on the cement composition, curing temperature, water to cement ratio, and cement fineness. High temperature resulting from heat of hydration may cause thermal cracking of concrete and consequent reduction of mechanical properties.

Calorimeters

Two versions available: with standard Beckman thermometer and with digital high resolution.

Standards EN 196-8 ASTM C186
