摘要：
Along with the construction of resource-saving and environment-friendly society, extensive researches on environmental protecting and resource saving have been made in the field of construction industry, but the quantitative evaluation of the resource consumption and environmental impact in the process of construction has always been difficult to obtain. The paper focuses on the quantitative evaluation of resource depletion , establishing the quantitative evaluation of resource depletion effect according to the life cycle impact assessment and equivalent coefficient method, and then determines the equivalent coefficient of the resource based on coal; makes the quantitative evaluation of the concrete raw material consumption and resource depletion index under the analysis of several different strength grades of before and after adding fly ash concrete, and at last the corresponding proposal to lower the impact, which can be used as a reference basis for the green risk of construction project and sustainable development is put forward.

摘要：
Since the asphalt overlay of freeway in Hubei Province was opened, it appeared undue early diseases. The diseases mainly appeared in the surface layer. Through the disease investigation, construction data lookups and on-site samplings of SMA-13 surface layer, the three main reasons of early diseases are indicated. They are unclean raw materials, loose control of mixture proportion and unreasonable construction site management. This paper analyzed the generation mechanism of diseases in SMA pavement from every involved respect. At last, the suggestions about construction control measures were put forward to prevent early diseases．

摘要：
It is a problem on building energy efficiency of how to improve the heat insulation performance of building envelope, to make the building outer wall has good heat preservation effect, and to keep the necessary seismic performance. Exterior wall thermal insulation engineering, which is a key part on building energy conservation engineering construction quality acceptance and on building energy efficiency design, is an important part in building energy efficiency projects. Therefore, it is necessary to study the seismic performance based on the fact that the building is building energy efficiency. By the research on exterior insulation materials, the analysis on the performance of external thermal insulation materials currently used, and the research on the factors affecting the seismic performance of external thermal insulation material, It provides a guidance on evaluating the external wall thermal insulation material performance and quality, ensuring the quality of external thermal insulation material, and it is expected to achieve the effect of building energy efficiency.
摘要：
Domains and size effect of Curie temperature in BaTiO3 nanoceramics has been studied in this paper. We have calculated Coulomb interaction in a single domain of multi-domains BaTiO3 grain, and obtained Curie temperature at various grain size. The results show that along with the grain size decreases, the change of Coulomb interaction depends on type of domains. 90 degree domains cause Coulomb interaction increase and Curie temperature moves to high temperature; 180 degree domains make Coulomb interaction weak and Curie temperature moves to low temperature. The results are compared with experimental data.

摘要：
This paper synthesizes information obtained from a comprehensive literature review and agency surveys on the state of the practice of fixed automated spray technology (FAST) systems. Experience with FAST systems in North America and Europe has revealed a mixed picture. On the one hand, several studies have indicated reductions in mobile operation costs and significant reductions in crash frequency, resulting in favorable benefit-cost ratios. On the other hand, there have been a variety of problems related to activation frequency, system maintenance and training. Installing a FAST system is complex and the challenges are often site specific. However, the evaluations cited show that FAST systems can be cost-beneficial if their locations are carefully chosen and if the system is supported with reliable environmental sensors. Finally, it was found that application of FAST systems in North America have recently increased.

摘要：
The strength and durability are the main design parameters of high performance concrete. Concrete should be strict attention to the requirements of various raw materials and mix proportion design in the production process. Engineering example shows that high performance concrete has good durability, economy and environmental protection.
