The results of the compressive strength and flexural strength test are shown in Fig.1, where each value is averaged from the results of three individual tests.
Fig. 1.
As also seen from Fig.1, the increased porosity indeed led to some loss of the strength although minor.

An extension of this approach is the consideration of pressure dependent friction coefficients, as it is shown in Eq. 1.
Kudo, Effect of Surface Topography of Workpiece on Pressure Dependence of Coefficient of Friction in Sheet Metal Forming, CIRP Annals (1998) 479-482. ].
µp=µ0∙pp0n-1 (1) The formulation of the pressure dependent friction model depends on three different variables.
It is defined in a value range between 0 ≤ n ≤ 1, like in Fig 3.
Table 1 shows the parameter values of the experimental design.

After choosing the appropriate K.C. with S.J., transforming it to the K.C. with multi-joint by applying the following methods:
(1) Partial shrinkage of a polygonal link of the K.C. with S.J.
Obviously, the number of the rims can be shrunk should be less than the single-joint number of the link, that is, as shrinking a n-polygonal link, the number m of the rims can be shrunk must meet: 1≤m≤n-1, hence, it is just called the partial shrinkage of a polygonal link.

where n > 1, m = 1 − 1/n, α > 0 [L−1] are empirical soil parameters, and capillary pressure head

In (5), we replace ∂xhc = ∂hc ∂Sw ∂xSw = fc(Sw)∂xSw, where fc(Sw) := − 1 α(n − 1) 1 (1 − S1/m w )m S1/m w .
Then, we can solve only one PDE in terms of Sw which reads Φ∂tSw = Ks µw ∂x (D(Sw)∂xSw + qtµn kw ρkw + kn + kwkn µkw + kn(1 − ρ)ω2 g (r0 + x)) , (6) where D(Sw) = a(Sw) b(Sw)fc(Sw) with a(Sw) =(1 − Sw)1/2 (1 − S1/m w )2m S1/2w (1 − (1 − S1/m w )m)2 , b(Sw) =(1 − Sw)1/2 (1 − S1/m w )2m + µS1/2w (1 − (1 − S1/m w )m)2

The pH values were measured after stirring of PCMs with deionized water (ratio 1:2.5) for 1 h and stabilization for 1 h (Multi 3510 IDS, WTW, Germany).
Radiometric analysis All solutions used in the experiments were spiked with 137CsCl (5.406 MBq mL-1; CsCl 20 mg L-1 in 3 g L-1 HCl) solution obtained from the Czech Metrological Institute (Czech Republic).
GW has the lowest SSA (6.69 m2 g-1) and shows high Cs adsorption capacity comparable to PC with highest SSA 221 m2 g-1.
