Building exterior wall;Economic benefit;Economic evaluation;LCA
摘要：
Building exterior wall full life cycle assessment is the whole life cycle of various building materials, components production, planning, design, construction, operation and disposal phases in the material energy flow generated by the economic benefit, social benefit and environmental benefit,which is the sum of the evaluation. Full life cycle assessment is a very broad concept, it is to do the comprehensive analysis of the life cycle process, including the environmental systems, energy systems, natural resources, human health and so on. various aspects are to assess the influence of the potential, and ultimately to find ways to improve. Exterior wall full life cycle of economic evaluation model is established, the core content is a comprehensive economic evaluation of the scheme of building external wall structure, economic benefit evaluation of different exterior design, which provides the strong basis for the adoption of reasonable solution.

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：
The durability of sealing materials for road joint plays an important role in service of roads. The durability of silicone rubber sealant was studied by way of the testing its properties of liquid resistance, chemical resistance, alternate freezing and thawing stability and adhesion at various temperatures. The results evident that silicone rubbers have good thermal characteristics, chemical resistance, and environmental stability, which make this class of materials very attractive selection for use in the outdoor applications.

摘要：
A wavelet estimation method is presented herein to estimate deep pit settlement. In this method, the pit settlement is decomposed into the trend settlement and the stochastic settlement by using Wavelet Analysis based on the characteristic of influencing factor. The model identifier is established by using artificial neural network (ANN), and trained to approximate the trend settlement. Then, the prediction controller developed could be applied for estimating the actual settlement. Finally, the verification examples show that the WIAN is an effective tool for predicting the pit settlement dynamically , high precision could be expected and achieved.

摘要：
There is little provision about construction in the assessment system for green building in China, but green construction plays an important role in green building and it is a trend that the assessment system for green building should include the green construction in China. Based on contrasts of evaluation standard for green building, combining with operation experiments of green Olympic building assessment system, difficulties in developing of green construction industry in China is proposed such as policy, time, concept and materials. Thus, popularizing measures for green construction are suggested, including extending standards for green building, establishing owner inspiriting system and building system, developing popularity effect of green construction.
摘要：
This investigation aimed to study the interaction between concrete substrate and silicone rubber sealant. Several surface treatments were applied in order to obtain different levels of surface roughness in concrete substrates. The bond tensile test showed that abrasion and solvent cleaning methods improved the bond strength relative to that of untreated substrates. The effects of silane coupling agents on the bond strength was studied via two methods of application of the coupling agent, namely, (a) pre-treatment of concrete substrate in an aqueous solution of silane, and (b) adding silane to the silicone rubber sealant as an integral blend additive. No significant differences in bonding values were noted between the two methods. An increase in the amount of silane coupling agent increased the bond strength of the silicone rubber sealant, but beyond a certain point, further increases in the amount of silane lowered the bond strength. As the amount of silanes increased, the failure mode of the samples changed from adhesive failure to cohesive failure. Scanning electron microscopy and contact angle methods were employed to investigate the interface. The results strongly suggest that interface adhesion and treatments are crucial factors in creating a durable bond interface between substrate and sealant.
摘要：
In this paper the micro mechanism of BaTiO3 ferroelectric phase transition is studied based on the thermodynamic model using electron cloud model, and further the Curie - Weiss law is explained. The results indicate that the contraction of the electron cloud, as the temperature decreased through Curie temperature, causes oxygen ions shift the equilibrium position, and the Coulomb attraction makes Ti ion shift the equilibrium position causing phase transition; With temperature rising, the ion displacement polarization decreases owing to the electron cloud expansion effect, and the variation of dielectric constant with temperature follows the Curie - Weiss law.
