When the depth of holes meet the design need, the building materials are filled in the hole and compacted by column-hammer from the bottom of hole to the ground.
Finally, the pile and soil work together and form the composite foundation [1].The building material of made-up pile is mainly the building waste or lime sandy clay mixture.

Materials and methods Plant material Seeds were collected from 6~7 year old S. pohuashanensis trees cultivated at Heilongjiang Forest Botanical Garden in Harbin.
The bags were designed with two different sides, one kraft paper (for ventilation), and the other a transparent polyethylene material (light transparent).

(3) Construction utilization With the development of social economy, rapid advancement of engineering construction placed more demands on new construction materials such as sediment.
In the Xiaokaihe irrigation district, 3 new material factories were built beside the desilting pool.
(2) With the development of sediment science and utilization technology, more and more attention has being paid to the sediment properties as natural resource.

The sixth international conference on cement and concrete and CANMET/ACI concrete technology conference on sustainable development undertaken by Chinese society of silicate, Canadian mineral energy technology center,American concrete institute and Chinese building materials science research institute was held in xi 'an from September 19 to 22, 2006.
Throughout the development process of human civilization construction, concrete material has been put into the production and use as early as the beginning of 19th century.It has become the most widely used building material in the construction industry.
Concrete is mainly composed of coarse aggregate (stone) and the fine aggregate (sand), the two materials account for 75% in total concrete.
III.The application of recycled concrete in road engineering In the field of the road engineering, concrete is the most abundant material in its dosage, and is also one of the most widely used building materials.

Phase Composition and Crystal Structure Study Xiang Wei1,a , Mufit Akinc 2,b 1 Department of Materials Science and Engineering, Iowa State University, Ames, IA 50011, U.S.A 2 Department of Materials Science and Engineering, Iowa State University, Ames, IA 50011, U.S.A a xiangwei@iastate.edu, b makinc@iastate.edu Keywords: Bioceramics; Resorbable; Tricalcium phosphate; Silicon; Zinc; Crystal structure Abstract.
Both of these materials are more soluble and resorbable than stoichiometric HAp and therefore may be incorporated into bone more readily by osteocytes.
Moreover, the osteoconduction and osteosubstitution can be increased by controlling the biodegradation of the materials.
Materials and Method The commercial reagent grade CaCO3 (Fisher, USA), NH4H2PO4 (Fisher, USA), ZnO (Fisher, USA) and fumed SiO2 (Aldrich, USA) were used as received.
