Measurements of electric resistance and amount of consumption of portl
andite were carried out in accelerated curing conditions by preparing
pastes of Fine Ceraments, fly ash, silica fume, kaolin, acid clay, zeo
lite and quartz activated with portlandite. Electric resistances of re
active pozzolans showed sharp rises except that of kaolin, whereas tha
t of as inactive material, quartz, showed no sharp rise. Electric resi
stances are proportional to the consumptions of portlandite except for
fly ashes. The electric resistance measurement method combined with p
ortlandite consumption measurement is useful to the rapid evaluation o
f pozzolanic activity.
