Research On Saving Materials Of Green Construction Based On3R1H

Construction industry consumes a lot of natural resources in our country, whichmakes the lack of per capita resources become more prominent, and seriously affect thehealthy development of the national economy. Circular economy is one of the economicdevelopment model which refers to recycling and reusing resources, the implementationof circular economy is the inevitable trend in the construction industry. However, theconstruction phase consumes the most building materials in the process of the entire lifeof the project. If implementation of construction materials with the principle of circulareconomy3R1H decrement, reuse, recycle and disposal can bring huge economic, socialand environmental benefits.The article analyses the present stage construction material consumption inconstruction industry and define the circular economy of constructionmaterials.Summarize the study and application of recycling economy in constructionmaterials both at home and abroad and analyze the insufficient. Summarize the relevanttheories of circular economy and green construction, come up with the difference ofsaving material between the circular economy and the traditional linear economy. Showthe advantages of using the recycling economy, defining the green constructionmaterials theory under the circular economy. On this basis, combine with the point ofgreen construction materials theory, make building materials of construction process asthe research object. From the reduction of raw materials, excess stock and recycle ofleftover material, regenerated waste recycling and disposal of waste, put forward3R1Hconstruction of green construction materials saving mode, points out that to adopt thenew material, improve the construction technology, design scheme and recycle theconstruction waste to realize the green materials saving. Introduction the greenconstruction material saving management under circular economy, Instruct theimplementation needs of how to promote saving material under circular economy.Finally, make a construction project of south China as a case for empirical analysis,summary the construction materials saving mode of this project, make a detailedanalysis about the effect of saving material.
