Abstract: Abstract. The carbon fiber-slag conductive concrete is prepared in carbon fiber and slag elementary material of function. Under the conditions of a certain amount of Carbon fiber, research has been carried out in different slag content. The electric mechanical effects of Imposing loads has been carried out. The results indicated that: slag can improve compression capacity. And the compression capacity can be reduced by adding some steel slag while adding some amount. Carbon fibre-slag concrete can be used as self-monitoring materials fracture by the electric mechanical effects

Displays the area superiority, promotes the CL structure, to fundamentally does well the construction energy conservation work, to promote the Qinhuangdao urbanization advancement to be imperative. This article through the investigation and study to the Qinhuangdao CL structure Production enterprise, introduced that the energy conservation characteristic of the CL structure, founded the the question which existed in the promotion of the CL structure, searched after the countermeasure exploration speeds up the CL structure promotion work.

Abstract: With the deepening of the energy conservation of the building, energy saving from the original design of building energy-saving gradually turned to the field detection and completion acceptance, which requires a corresponding energy-efficient means of detection. With the development of infrared technology, the combination of infrared technology and detection methods of building energy-saving, to further promote the development of building energy efficiency testing work. Compared to the traditional heat flow meter or hot-box method, infrared thermal imaging method has no effect on the measured object, detecting the surface temperature of quick reaction speed, accompanying with wide temperature range and high precision, is widely used in various fields of testing work, which has been particularly prominent in the thermal defect detection. In this paper, the method of infrared thermography is used to confirm whether the thermal defects exist in energy-saving construction or not. Testing results show that infrared thermography can accurately reflect the temperature distribution of building wall surface. Infrared thermal imaging to detect the building surface's energy efficiency, which is providing efficient and accurate means of detection for the evaluation of the building energy efficiency. This is to help carry out a comprehensive building energy-saving testing.

Abstract: The floor heating system of phase change energy storage (FHSPC), performing well in storing and releasing thermal energy, plays a significant role in using solar energy and low-priced nocturnal electrical power for heating. However, due to such problems as ineffective package and insufficient overall integration of phase change material, research of FHSPC has not made progress in practical application. This paper researches thermal storage effect of a new floor heating system of phase change energy storage using solar hot water as the heat source and double layers of capillary network as the heat dissipation end. Differential scanning calorimeter was used to choose capric acid as the main energy storage material. For a steady heating cycle of heating for 8 hours and releasing for 16 hours, acceptable thermal condition is observed in the test room. The new FHSPC could provide long span intermittent heating with little heat loss, therefore the intermittent energy source can be well utilized

Abstract: This paper presents an experimental study dealing with the toughness of heavy concrete based on the ASTM C1018. Mixtures including 0%, 0.5%, 1.0% and 1.5% of steel fiber content by volume are designated, which are developed based on a mixture used in Kuosheng nuclear power plant in Taiwan. Metallic aggregates of iron shots and iron ore take 48.8% by volume in that mixture. Test results reveal that the compressive strength and rupture modulus of heavy concrete turn out higher than those of normal concrete. In addition, flexural toughness of heavy concrete grow with the steel fiber fraction, which is valid and appropriate for construction of shielding structure and spent fuel cask.

Abstract: Industrial building energy consumption accounts for more than half of building energy consumption. In order to understand the situation of energy consumption of industrial building’s energy system in Shenyang located in China's northeast severe cold region, we investigated the distribution of industrial buildings and energy system’s energy consumption (HVAC, water supply and drainage, electrical system) of typical industrial buildings in Shenyang, it is found that the energy system’s energy consumption of Shenyang is great because of long-term neglecting of industrial building’s energy conservation. We must strengthen the designing of energy conservation, applying of new technology and supervising of industrial building to develop the potential of industrial building’s energy conservation.

Abstract: Combined Cooling，Heating and Power system(CCHP system) has potential advantages in areas of energy reliability, environment and economics. This paper analyses the system's principles and puts forward internal combustion engine CCHP system and builds a series of mathematical models of each part. The main purpose of this paper is the analysis of the annual total cost and energy saving rate, the results show that, compared with the conventional supply system, the CCHP system can save 1,060,000￥annual, the save rate is amounted to 22.1% and relative energy saving ratio could reach 13%. This study may provide with some reliable foundations on the application of the CCHP system.

Abstract: In asphalt pavement maintenance design the deflection of pavement strength and the drilling core examination of damage on each structure layer are required. This paper based on the advanced technology of the FWD and developed a link with the Benkelman Beam testing. It indicated that assessment of the usage information on each structure layer by using the Modulus Back Calculation was well matched with the core results; therefore, it improved the work efficiency to a new level.

Abstract: The expo 2010 in Shanghai from May 1st to October 30th has ended, after six months, 55billion dollars, and 73million visitors. According to the rules of the Bureau International des Expositions, the global governing body of Expos, all the pavilions on the expo site should be taken down. However that will put the Shang Hai Expo into dilemma, as which was characterized by its greenness, expo pavilions destruction will create tons of waste instead of “better city, better life”. Except for the China Pavilion and Expo performance centre, other pavilions have to wait to be chosen either remained or removed to other location. Therefore this thesis is trying to make some case analyses of the Expo pavilion in the history and explore the potential of the temporary building.

Abstract: Aiming to minimize fossil fuel use and environmental impacts caused by buildings, thermal design is one of the most effective approaches forwards ecological architecture. For any given region, ecologically thermal design has to follow the principles of ecological design, which need to be conditioned to the local situation. In this context, under the poor conditions of rural Northwestern China, the feasibility limited by budget and conventional resources for construction is the main challenge faced by ecologically thermal design for local buildings. Under the background, the methodology based on condition analyses and computer simulating experiments with TAS is involved in the study. Based on locally available building elements and technology the paper carries out a series of alternative techniques and feasible thermal design strategies for this region, aiming to reach the most effectively ecological approach. As a result, the relationship between the cost increase and improvement of building thermal performance resulting from each technique is reduced, so as to assist locals to design and construct the feasible ecological buildings according to their individual situations in economy, resources, functions and site condition. This illustrates an inspiring way towards the ecological architecture suitable for rural Northwestern China.
