Material and Methods Raw materials.The local hardwood waste from Reasak (Vatica spp.) collected from Makmal Kayu at Forest Research Institute Malaysia, Selangor, Malaysia.
Finally the bleached cellulose was soaked in 17.5% of sodium hydroxide (NaOH) solution at room temperature with time exposure 30min. this process later to remove the remaining amorphous materials.
Fig. 1 shows the morphology of untreated sample, R and treated samples, R1 indicating that the fibers in the untreated samples (Fig. 1) were bonded together by massive cement materials, which were obviously diminished after treated (Fig. 2).

In this context, diverse materials have been investigated in the search solutions for environmentally friendly.
As an alternative for reducing the environmental impact arises a new class of materials, the biopolymers.
This mixture forms a new class of materials which are bionanocomposites obtained from polymer blends with addition of chemically modified clays [4].

In ULS the effect of loads is increased by partial coefficient of reliability γF and the resistance of materials is reduced by partial coefficients of materials γM.
Tests of materials 30 tests samples were prefabricated during execution of the first set of the columns S1.
In spite of the fact that columns were fabricated with the same materials and the high attention for accuracy the differences of results are notable.

The main cause is that the foundation is composed of concrete structures and spring vibration isolator, which are two totally different materials.
The mesh generation of different damping materials is independent, and the boundary of material is considered as element meshing boundary, then the neighbored materials have common nodes.
Suppose there are n nodes containing the common nodes between neighbored materials, m materials of different damping, and the complex damping coefficient of material is .

But alloy material when receives the surface load, the high temperature forms the superficial oxide compound's chemical composition's change rule is with has not exerted load different [1,2].This immediate influence material operational performance.
(2) For the stretch load Cr5Mo material test specimen, it produces in the high temperature oxide compound Cr, Fe, the Mo three element content compared to do not have the load Cr5Mo material test specimen to increase obviously, showed that the load may change the alloy high temperature oxide compound truly the chemical composition.
