The building materials do not need to burn and raw-soil of the building come back to tract as fertilizer when the house is dismantled.
National Science and Technology Commission list the research of adobe building as a national research project in 1958, then universities and research institutes of Xi'an worked on a number of adobe materials.
The study is deficiency of adding other materials into soil to modify performance of raw-soil structure.
The territory of China is broad, so it is different selecting admixtures with soil and other building materials with raw-soil structure.
More types of soil, different materials mixed and different construction conditions make a larger difference in the performance of bearing wall.

Abstract.
Ramie fiber and polypropylene were used as raw materials,ramie fiber/polypropylene composites were prepared by compression molding process,the effects of treating the ramie fiber with silane coupling agent and compatibilizing the composite with maleic anhydride gafted polypropylene(MAPP) on the structure, melting and mechanical properties of the composites were studied,the effects of immersion time in water on the mechanical properties of the composites were also investigated.The results show that,both the modification with coupling agent and by means of compatibilizing agent can strengthen the interfacial bonding between the fiber and matrix in the composite,and also improve its thermal stability.All the modified composites have greater strengths and moduli than the unmodified ones when immersed in water for any periods,especially the impact strength of the MAPP compatibilized composite not only increases with immersion time in water dramatically,but also is improved from that of the
different composites means the material is more difficult to melt.So,it can be concluded from the result that both CRPP and MRPP have better thermal properties than RPP.
The water uptake of a material has relationship with its structure and properties,some researches have focused on the water absorption of natural fiber/polymer composites[4-5].
