from Kefalonia (Lk) and Arta (La) areas, and marbles from Asfendou, Crete (Ma) and Naxos Island
(Mn) was studied. Lime reactivity was studied in terms of specific surface area and slaking temperature. In all
cases the specific surface area displays a maximum at low firing temperatures decreasing thereafter. In rocks
with low porosity lime reactivity depends on calcite crystal size. Very small calcite crystal sizes comparable
to that of lime crystals yield lime with low reactivity due to low porosity of the end products. The lime produced
from raw materials with large crystal size has inferior reactivity due to kinetic constraints. In materials
with small calcite crystal sizes comparable to that of lime crystals reactivity of lime is controlled by porosity
