Different techniques for measuring heat of hydration of cement are discussed, and a sample holder designed specially for measuring isothermal heat of hydration is described. A particular characteristic of the sample holder is the vacuum mixing technique which ensures a momentary and homogeneous mixing of the water and the cement. This enables investigation of the rapid initial cement-water reactions. In addition, measurements at very low water-cement ratios are made possible with this technique.
