The analysis shows that the latex cement can be used for deep soft rock rheology theory and polymer materials similar simulation experiment.
The mechanical properties of the deep soft rock are impacted by the environmental deep rock mass and are difficult to be simulated by actual materials, it is relatively easy that the application of latex cement as the similar material to simulate deep soft rock.
This conclusion is consistent with the experimental data，it proves that a reasonable proportion of the latex cement can be used as a soft rock similar materials.

Because of their poor quality, the performance of PSL made from these waste veneer residues usually disqualified as structural materials [2].
Materials and method Materials.Poplar veneer strands were obtained from local plywood plant in Nanjing.
Flexural toughness index (ID ) is a parameter that reflect response of different materials to the flexural load, it is calculated as the ratio of Wp to Wi.

The fatigue resistance of HSS is a major concern since it is well known that the fatigue resistance does not increase proportionally to the static strength of such materials [2].
This means relatively limited data for the safe design and partially deficient understanding of the fatigue behaviour of these materials.

Converting such waste to useful materials such as adsorbents could solve their disposal challenges.
Commercially, the common precursor materials used for activated carbon (AC) production are coal and some agricultural by-products of lignocellulosic origin.
