The survey also found that, in the middle of reinforced concrete materials in some agricultural not applied correctly, such as the beam is not closed, structural column interrupted and the spacing is too large problem.
The choice of building materials to ensure the seismic safety performance of housing is crucial, not only to satisfy the requirements of building structure under the normal use of the strength, also to consider the seismic ductility.
Quality problems of the local farmers in the selection of construction materials exist.
Bars directly from the local building materials market, property indexes, for instance, mechanical properties, appearance quality and size and other performance can fluctuate wildly and is not up to the national standard.

Advanced cellulose function material, such as photoelectric materials, hybrid materials, biomedical materials and intelligent materials, has becoming the hot research area for the past few years.
It can offer a direct method for studying water behavior in cellulosic materials.
The length of linear cellulose chains expressed in the degree of polymerization (DP), varies with the origin and treatment of the cellulose materials.
In the early studies, different theories about the water sorption in wood materials were proposed.
