The peak occurs earlier and the amount of heat developed in
the sample with NaOH is higher, even up to 28 days. The acceleratory effect
does not reflect in increased strengths. The lower strengths in NaOH treated
samples is attributable to the plate-like and reticular morphology of the
hydration product with poor bonding characteristics.
