The batch reactor was designed to scaling-up from a laboratory-scale approximately 5 g to approximately 300 g of the feed raw materials.
Therefore, many researchers have interested to use agricultural waste as raw materials.
For this study, the nanosilica derived from rice husk will be used as an additive for cement materials to improve the compressive strength in the next study.
The raw materials were started from the rice husk ask (RHA).

Heat-insulation materials produced from refractory fibers possess this combination of properties[2].
Experiments Materials Aluminum silicate fibers were from Zhangqiu Tiantong Refractories Plant.
It is probably because that the differdent bulk density indicate the changes of materials’ porosity and the pore size, which would have a great influence on the thermal conductivity of insulation materials indirectly[8].
The mass ratio of materials and corresponding tensile strength of the cardboard were shown in Table. 1.

From the perspective of material science, dynamic-static friction ratio is supposed to necessarily be identical or constant for a material, however, in many cases, natural soil deposits commonly contain laminated infillings or interbeds, by which the dynamic-static friction ratio are caused to be diversified.
Dynamic side friction can be investigated without considering the materials of pile.
