Physical characteristics of the samples, including moisture content, specific gravity, dimensional changes, total porosity, and water sorption and mechanical properties (compression strength and compressive modulus of elasticity), were calculated using standard equations (Siau 1995).
These analysis were carried out in order to evaluate the petrophysical parameters such as the shale volume (Vsh), total porosity (PHT), effective porosity (PHE), water saturation (Sw), hydrocarbon saturation (Sh), and pay zone.
Physical parameters analyzed were wet bulk density ([D.sub.W]), dry bulk density ([D.sub.D]), total porosity (TP), air filled porosity (AFP), easily available water (EAW), buffer water (BW) and remaining water (RW).
In the mixture soil + organic compound, comparing with the remaining studied substrates, it was verified that in spite of the best results of P, K, Mg, Ca, Ca + Mg, Zn, Mn, B and CTC, the highest density and lowest total porosity were observed with the highest distribution rate of particles in the smaller particle size <0,25 mm (37.01%) and in the particle size from 0.25 to 0.5 mm (22.49%) (Table 1).
The second method used to determine the total porosity of the cryogels was based on the method of moments used for packed beds [19].
Generally, porosity has two main types: total porosity and effective porosity.
The proprietary Enhanced Biochar production process controls particle size distribution, total porosity, dioxin levels, pH as well as other material attributes to provide a high-impact and consistent carbonrich material.
In these systems, the total porosity levels attained after curing and drying (50-120[degrees]C, 45-60%) were close to the volumetric amount of water initially added during mixing (40-55%).
Total Porosity. The pores in the [beta]-TCP scaffolds and the micro-tubes in the scaffold were responsible for the total porosity.
