Specific Surface Area - an overview ScienceDirect

The specific surface area of lime–natural pozzolana pastes increases gradually with time up to 35–100 m 2 /g after 90 days of curing. 89 In bottle hydration (water/binder = 12.5), the specific surface area of the hydrates is higher and can be greater than 150 m 2 /g after 1 year of curing, depending on the type of material and lime/pozzolanic material ratio. 126 For a lime/pozzolana ratio up to at least 0.6, combined lime progressively increases.

Hydrated Cement Paste - an overview ScienceDirect

The measurement of the specific surface area (SSA) of hydrated cement pastes is known to be delicate both on fresh (Yamada, 2011) and hydrated cement paste (Garci Juenger and Jennings, 2001; Odler, 2003; Thomas et al., 1999). This is due to the (partial) dehydration of hydrates in the drying process during the measurement, in particular the BET measurement.
