Abstract


Rapid development of construction industry needs to produce a large number of concrete and also due to the dismantling of the old buildings have a lot of waste concrete. Promote the use of recycled concrete can not only save natural mineral resources, but also reduces the waste pile or landfill concrete wanton pollution of the environment. Recycled aggregate due to the current production process more complex, the production cost may be higher than the natural aggregate, if only in order to measure the economic benefits of recycled concrete will hinder its economic application and also one-sided, recycled concrete economic from the environmental and economic benefits should be two aspects to consider. Past studies have only life-cycle assessment (LCA) the environmental benefits of recycled concrete evaluation to get a comprehensive evaluation of their environmental and economic results. In this paper, LCA (Life Cycle Assessment) and LCC (life cycle cost assessment) recycled concrete methods for integrating environmental and economic comprehensive evaluation.First, this study based on domestic and foreign recycled concrete and major application areas, environmental and economic analysis of recycled concrete set of objects. Then, in the LCA (Life Cycle Assessment), based on the type of improvement of its environmental impact weight calculation method used to measure the environmental impact of social factors in willingness to pay in lieu of the traditional weight of the level of the LCA analysis. Combine the characteristics of recycled concrete calculation to determine the economic and environmental factors weight. Of recycled concrete in the country on the basis of technical studies, use of LCA (Life Cycle Assessment) and LCC (life cycle cost assessment) integration methods, the establishment of recycled concrete life cycle environmental and economic performance assessment system, and one of the key process of analysis, adjustments and settings. Finally, the optimization of recycled concrete technology program designed to make recommendations to promote the use of recycled concrete with domestic problems to be solved, mainly for non-technical factors that meet the conditions of our country’s industrialization strategy of recycled concrete and relevant policy recommendations.analysis, adjustments and settings.
