Some correlation between the quicklime reactivity and the specific surface area is found. The work demonstrates that industrial furnace calcining large limestone pellets, leads to low reactivity quicklimes both because the calcination temperature is too high and the CO 2 pressure is too elevated.

The results of the test series with the further mid-range quality CC DE-05 is shown in Fig. 5 d. According to reactivity testing in chapter 3.1 the reaction heat after 7 days is almost the same for DE-04 and DE-05, however, the calcined clay DE-04 appears to react much slower as shown by the strength evolution between 1 and 7 days.
