Unfortunately, the negative prejudices on earthen materials are still very rooted because they are considered as vulnerable materials.
But the Clay material is superior to industrial building materials.

The traditional product process is from the design → manufacturing → operation → maintenance to scrap, after product disposing, some renewable materials are for recycling, and others non-recyclable materials are for environmental protection treatment.
Components can be recycled to reuse & materials regenerating or security processing.
And it can not only reduce the waste of materials and save the energy, but also prevent the pollution of environment.
The recycling of waste material will become a high quality of recycled materials.

Therefore, construction materials at Project B were covered and stored in good condition.
Table 3 shows the calculation of wastage level for these materials.

Appear afore–mentioned phenomenon maybe due to the following reasons: ①there is a big stiffness difference at the Bridge-Subgrade joint, which leads to a downward additional impact caused by train wheels when the train leave the bridge , and increases the vertical deformation of the track ; ② the abutment is comprised of masonry materials.

Materials and experiment NR and SIR10 were produced in Indonesia.
The nano ZnO is added more, the resisting ability of thermo-oxidative is better for the composite materials.
After 100°C×48h thermo-oxidative aging, the tensile holding rate of nano ZnO/NR composite materials is 90.64%, higher than that of normal ZnO/NR composite materials.

In addition, material at the near-load end enters the nonlinear stage.
The eccentric load that the specimens sustain is basically the same with increasing load as the members go into the material and geometric nonlinearity stage.
