Quasi-adiabatic calorimetry performed on concrete specimens (known under the French acronym QAB) is a method first proposed at the LCPC Laboratory in the 1980’s; it involves transposing to concrete the same procedure applied for the standardized determination of cement hydration heat (NF EN 196-9, which replaces Standard NF P 15-436). This input is essential for predicting, by numerical simulation, the thermomechanical behavior of structures. The present article offers a description of the calorimetry equipment and its performance, along with the various calculations that yield: the amount of heat released, the kinetics of this release (if the test had been adiabatic), heat flux, chemical affinity and degree of hydration. The principles behind QAB calorimeter calibration are reviewed and the magnitudes of influences assessed in order to estimate uncertainty in the heat release calculation. On the other hand, the level of dispersion inherent in the material still needs to be estimated.
