8.2 Calorimetric Procedure, Partially Hydrated Sample—
For the heat of solution of the partially hydrated sample follow
the same procedure as for the dry cement described in 8.1, but
use a 4.18 6 0.05-g calorimetric sample of the partially
hydrated cement, weighed to the nearest 0.001 g (see Note 4).
Calculate the results on the ignited basis.
