The work in detail is that construction agent shall set up a special account of the project construction finance, the financial management department shall appropriate in installments to construction agent by the financial plan, and construction agent shall pay the capital to the main contractor, the engineer, the procurement contractor of plant and materials etc.
On the other hand, Construction agent shall sign the supervision commission contract, survey and design contract, construction contract and material procurement contract, which involve in extensive contents, complex cases such as the undefined scope of risk, the contradictions of contract and the two explanations of significations etc.
The contract clause should be ready seriously, avoid the hazard and the occurrence of engineering variations and claim for compensation, and decrease the limitation, while it is made for the contract of engineer, reconnaissance and design, construction and material stock.

DHM is a plant flavonoid, most commonly extracted from natural plant materials, such as the fruits of Hovenia dulcis (Yoo S M et al., 2006) and the leaves and stems of Chinese vine tea (Ampelopsis grossedentata) (Du Q et al., 2002; Zheng C et al, 2006).
Materials and Methods Chemicals and Reagents DHM (95%) was obtained from Fine Chemical Research Laboratory of Guanzhou University.

Effect of high–temperature heat treatment on mechanical property of Cr-geopolymer composite Mei-rong WANG1, a, Yi ZHENG1, b, De-chang JIA2, c and Yu ZHOU2, d 1 Shandong Provincial Key Laboratory of Ocean Environment Monitoring Technology, Institute of Oceanographic Instrumentation, Shandong Academy of Science, China 266001 2 Institute for Advanced Ceramics, Department of Materials Science, Harbin Institute of Technology, China 150080 awmr21c@163.com, bbitzhengyi@163.com, cdcjia@hit.edu.cn, dzhouyu@hit.edu.cn Keywords: Geopolymer, Composites, Chromium Particles, Heat Treatment, Mechanical Property Abstract.
Geopolymer materials are regarded as the most promising substitute for aircraft composites and cabin interior applications instead of polymer materials in a research program by U.S.
In order to improve the thermal conductivity and mechanical properties of geopolymerical materials, metal particle was chosen as the reinforcement in our investigation.

Material model calibration.
Tensile tests on coupons obtained from identical steel plates, beams, and columns were used to model A572 G50 steel materials, which were then used numerically to create all-steel I-beams, columns, and strengthening plates.
