Abstract: This paper introduces the concept of green building and sustainable development as well as the relationship between them,combine with Weifang art and cultural center project,explains the design idea of green building and the concept of sustainable development,Finally,it proposes that only to coordinate the relationship among the construction,natural,human and society,can really achieve the green building which is sustainable development.

Abstract: This document explains and demonstrates how to design green industrial building . The article analyzes how to implement green industrial building focus on research of green industrial building project design according to evaluation guidelines and explanations of green industrial building. Provide passive design methods proposal for green building. In order to design to create comfortable and productive work environment for the users the construction details shoud be focused on flat and shape ,control,section flat and lighting external space in hot summer and cold winter zone.

Abstract: This paper, based on the relationships of Architecture Environment ,conducted systematic research on the means of climate environment design, probed into the tactics of feasibility of climate environment in the architecture design and architecture technologies ,and low-carbon building is not only the demand of the protection of source and energy with ecological environment but also the one that can meet peoples requirements for easy and comfortable ,economic and energy conservation inhabitation environment. When respecting nature, the process of optimizing architectural environment should be promoted actively with creation so as to obtain comprehensive benefits of natural, economy and ecology Keywords-Nature; Low Carbon; Ecological Architecture; Environment

Abstract: As the latest concept of ecological protection, community co-management principle was considered to be the best way to reconcile the contradictions between conservation of natural resources in ecoregion and the development of surrounding community. The Xing'an ecological function area is an important water conservation forest ecosystems base of China, priority must be given to its planning sustainability of ecological benefits. Therefore, we introduce community co-management principle to Xing'an ecological function of planning for sustainable development. By enhancing propaganda and education, the assistance to community information, technology and services to enhance the enthusiasm of the community residents, develop the eco-economy, and raise awareness of ecological protection, ultimately achieve a win-win situation of ecological conservation and the community social and economic interests.

Abstract: Based on the whole development plan of vocation tourism in Badong country, the development status and problems were analyzed for Yesanguan ecological vacation tourism in western Hubei province. The strategic orientation, strategic targets and measures of Yesanguan ecological vacation tourism are proposed. Through resource integration, administrative merge and unified plan, the new ecotourism products of southeast Badong are formed, and the Yesanguan tourist hub and Lucongpo alpine leisure international club would be built.

Abstract: This paper reports on part of an ongoing experimental program at The University of Adelaide on FRP-concrete-steel composite columns. The results from eight FRP-concrete-steel double-skin columns (DSTCs) that were tested under constant axial compression are presented. The key parameters examined included diameter, thickness, and strength of inner steel tube. The results of the experimental study indicate that concrete in a DSTC system is confined effectively by FRP and steel tubes. The results also indicate that increasing the inner steel tube diameter leads to an increase in the ultimate axial strength and strain of DSTCs. No clear influence of the strength of inner steel tube is observed on the ultimate condition of concrete in DSTCs. These results are presented together with a discussion on the influence of the key parameters on the compressive behavior of DSTCs.

Abstract: The resistance to chloride ion penetration of the concrete added with slag powder and fly ash is studied in this paper. The tests show that: adding slag powder and fly ash to concrete can improve the concrete’s resistance to chloride ion penetration; if only adding slag powder, the larger the adding content and the longer the test age, the better the concrete’s resistance to chloride ion penetration; if only adding fly ash, the longer the test age, the better the concrete’s resistance to chloride ion penetration; at the age of 28, 56 days, if the fly ash adding content is 30%, the concrete’s resistance to chloride ion penetration is optimal, while at the age of 84 days, if the fly ash adding content is 40%, the concrete’s resistance to chloride ion penetration is optimal; if adding both slag power and fly ash, the larger the adding content and the longer the test age, the better the concrete’s resistance to chloride ion penetration; if the test age and adding content remain constant, for the concrete’s resistance to chloride ion penetration, it is the best when adding both slag power and fly ash, it is good when adding only slag power, and it is poor when adding only fly ash; for the influences of the test age on the concrete’s resistance to chloride ion penetration, it is maximum when adding only fly ash, it is moderate when adding both slag powder and fly ash, and it is minimum when adding only slag power; and the larger the adding content, the greater the influences of the test age on the concrete’s resistance to chloride ion penetration.

Abstract: The glass ceramics bricks were prepared by the method of isostatic pressing and one time sintering using fly ash and glass powder as raw materials. X-ray diffraction experiment was performed to identify the main crystal phase. The influence of sinter temperature on the hardness was studied. It was concluded that the main phase were anorthite and albite. The hardness of sample which contains 60% of fly ash attains 766.79MPa when the sintering temperature was 1110°C .The hardness of sample which contains 50% of fly ash attains 780MPa when the sintering temperature was 1075°C.

Abstract: In this paper, the role of fly ash and slag powder on the concrete are introduced. Through the experiments that mixing up fly ash , slag powder or two kinds of mineral admixtures in the concrete, the characteristics of property of concrete at different times are learned. The results show that the property of concrete are better when two kinds of mixtures are used than mixing one of them, and the most appropriate proportion of mixing is 30%~40%.

Abstract: Reactive powder concrete (RPC) is an ultra-high performance concrete (UHPC). Cement and silica fume content of RPC are generally rather high compared to the conventional concrete. The aim of this paper is to decrease the cement content of RPC by using phosphorous slag powder. Firstly the effect of grinding time on the activity index of phosphorous slag was investigated. And then, the mix proportion design of this UHPC containing phosphorous slag powder and silica fume was done through orthogonal design. The results indicate that the utilization of phosphorous slag powder in RPC is feasible when the dosage of phosphorous slag powder is about 35% (by weight of the binder) and the water-binder ratio is less than 0.18. By substituting phosphorous slag powder for a part of cement and keeping the water-binder ratio at about 0.14, UHPC specimens whose content of mineral admixtures, including phosphorous slag powder and silica fume, was about 40%~50% (by weight of the binder) were obtained after they had been cured in 80 °C water for 72 hours. The compressive and flexural strength of those specimens was more than 150 MPa and 20 MPa respectively.
