Gravel content is an important factor affecting the mechanical properties of clay-gravel mixtures.
The shear strength of mixtures composed of clay and aggregates is affected by the ratio of clay-to-aggregate by weight [4-8].

Various specimens, which summarized in Table 1, were prepared to evaluate their properties and to discuss the effect of the ratio of composite to foamer (C/F, w/w) and the ratio of n-HA to PA66 (n-HA/PA66, w/w) as well as the weight of mixture used per mold (W, g) on the final performances of porous species.
XRD (X'Pert pro-MPD, Philips) and FT-IR (Thermo Nicolet 170SX FT-IR Spectrometer) were employed to investigate the influences of the thermal-pressing procedure on the properties of n-HA/PA66 composite after formation of porous species.
These results suggest that the weight of the mixture used per mold is one of the key factors affecting pore structure and porosity.
The results above mentioned show that not only porosity but also pore structure affect the mechanical performance of porous material dramatically.
