Abstract
The pozzolanic activity of DK is the principal factor and heat evolution increases with respect to pure PC mortar, during the first 15Â h. The presence of hydrated silica (silanol groups) in DK increases the pozzolanic activity especially before and during induction period. The acidic silanol sites are capable of a fast acid-base reaction with the alkalis and with any Ca(OH)2 present in cement during the induction period.
