The fabric tortuosity test was performed using a mercury porosimeter
and the tortuosity relation is presented in Eq.
(ASAP 2020 model from Micromeritics) was used to determine the BET surface area ([S.sub.BET]) - based on [N.sub.2] at 77 K (SKAAR, 1988) - the microporous area ([S.sub.M]), the Langmuir surface area ([S.sub.Langmuir]), the external surface ([S.sub.external]), the total pore ([V.sub.P]), the micropore ([V.sub.MP]) and mesopore ([V.sub.MSP]) volumes and the average pore diameter (D) of the C[O.sub.2] AC.
Estimating effects of compaction on pore size distribution of soil aggregates by mercury porosimeter
. Geoderma, v.
The morphology of cement hydration products was observed by JSM-6700F scanning electron microscopy, and the pore structure was measured by AutoPore IV 9500 mercury porosimeter
At the age of 28 d, a mercury intrusion porosimeter
(MIP) was used to determine the pore characteristics of the hardened pastes.
The helium porosities ([[phi].sub.g]) of all the investigated rock core samples were determined by helium porosimetry using a helium porosimeter
based on Boyle's Law.
On this basis, and using HPG-100 helium porosimeter
, the effective porosity, and bulk density of the sample were calculated.
The N2 BET method (Narkis and Ben-David, 1985) employing a Quantasorb surface analyser, QS/7, mercury intrusion porosimeter
, Micrometric model 9310 (Orumwense, 1996) was used to measure the surface area and porosity of the fly ash.
The morphology and specific surface area of pine biochar were determined at Scientific Institute of Thermal Insulation of Vilnius Gediminas Technical University using scanning electron microscope and mercury porosimeter
Quantachrome Poremaster PM-33-12, respectively.
Porosity was measured using a helium porosimeter
developed by Core lab.
