Compared with traditional cement processing methods, dry-mix mortars are more environmental friendly by reducing air pollution or waste production on construction sites. It can also reduce carbon dioxide emissions, helps to keep the construction site clean, and allow for more flexibility in storage space for materials while reducing cement redundancy after the cement finishing is completed. It can...
On the basis of discussing the present situation of urban transportation environment in Shanghai, this paper analyzed the environmental problems and its cause during the course of urban transportation development. In terms of sustainable development, the strategy that urban transportation development and environmental protection should be carried out simultaneously was proposed as well as its concrete...
The stratagem of sustainable development challenges the traditional construction project management objectives. The author does a qualitative investigation aiming at practices of Chongqing's local project management, various passive influences on environment arising from construction activities are identified. This paper points out that the traditional construction project management only focus on...
In order to improve the quality of low-carbon road design, this paper analyzes an impact of carbon emissions at road design period, highway construction period and operation period, and proposes corresponding emission reduction measures. Besides, it develops the search function of WEIDI software as a medium, then design time is saved effectively, and the accuracy of low-carbon design is improved greatly...
A huge quantity of solid wastes produced by Wenchuan earthquake has brought us a great challenge to dispose and also aroused people's great attentions to search for a rational and effective method to deal with such mass wastes, as well as the recycled aggregate concrete used in construction has been heated discussed worldwide. In this paper, the essentiality and feasibility of using recycled aggregate...
Heilongjiang province has the largest area for agriculture in China and its agriculture is a big non-point source for water pollution. The policy reasons of this problem were investigated extensively and recommendations were put forward in this paper. Policy reasons that lead to agriculture as a non-point source of pollution in Heilongjiang province included: unbalance of economy growth and environmental...
The list of highway planning, surveying, design and construction should pay attention to environmental issues are discussed at this stage of highway construction in the importance of environmental protection, on how to do the work of road construction and environmental protection put forward specific measures, and to be explored. The paper analyzes the relationship between the highroad prospective...
Building wall materials containing plant fiber products, performance is better alternative, practical, strong products, The paper made an introductory of its Insulation structure theory, discusses its energy saving, ecology, environmental characteristics, will be the development of new energy-saving green building materials play a positive role in promoting.
Recent advancements in various structural systems have made the selection of the appropriate structural system for a specific project a challenging decision making process. This process involves different economic and technical criteria representing the availability of experienced technicians and engineers and necessary machinery and construction materials. Economic life cycle, environmental protection...
Selecting an appropriate air-conditioning system for villa is important for maintaining a comfortable indoor environment, energy saving and environmental protection, etc. The paper gives a study on selection of air-conditioning system for villa based on value engineering methodology. According to the principle of value engineering, a mathematical model for selection of villa air-conditioning system...
Building construction has an enormous and increasing impact on environment, and sustainable construction can lead to environmental protection. At the same time, the selection of green building materials is a critical point to realize sustainable construction. In this paper, considering the properties of building materials, a systematic method based on life cycle assessment (LCA) theory is put forward...
Land desertification has become an increasingly serious global environmental problem. The land desertification situation of Xiaobazi Township, Fengning County, Hebei Province is one of the most representative areas in capital circle. Desertification land control is a complicated system project concerning ecology, economics and society. Aiming at the two difficult problems of ecology and poverty, through...
With the recent development of transport infrastructure construction, the ecological and environmental protection issues, caused in the construction period and the operation period of the road, especially the freeway, becomes increasingly prominent. And the runoff pollution of road surface is the one of the most serious aspects, such as the pollution by heavy metal ions and nitrogen compounds. If...
The application of construction technology of hydraulic fill with sand in high type road in China had made numerous social and economic benefits, but from some successful examples of using this technology, we can know that most of them have certain limitations and it has not developed completely. In this paper, the research of preparatory work, construction technology, environmental protection, quality...
According to the characteristics of green construction, this paper defines the key indexes in green construction assessment system which includes resources utilization, environmental protection and construction management. It also builds up green construction assessment model in which relationships among indexes are established. Back Propagation Neural Network (BPNN) optimized by genetic algorithm...
As the environmental problem is emphasized by the whole society increasingly, the needs and demands of the environmental data sharing and service are becoming more and more urgent. In the course of constructing State Environmental Data Center (SEDC): organizing, standardizing and strengthening exchanges of data and information between sections; setting up environmental foundation database of the national...
New energy-saving composite wall structure is a kind of new residential building structure system characterized by waste utilization, saving energy, environmental protection and good aseismic performance, which is mainly constructed with pre-cast multi-ribbed composite slabs, concealed frame and floor by means of assembling and casting. Based on the previous test of the wall, heat transfer and thermal-insulating...
CSG method is a new technique proposed for RCC; the key of this technique is the application of CSG (cement sand and gravel) to dam construction. CSG is a material, which can be considered as a lean RCC, made by adding a little amount of cement to rock-like material such as riverbed gravel or excavation muck that can be obtained easily from dam sites, then mixing it briefly with simple equipments...
