Study On The Building Carbon Dioxide Emissions Based On Reinforced Concrete Structures

Construction industry is a pillar industry of national economy, China is in theindustrialization and modernization of the transition and the peak of economicdevelopment, building market is prosperous and it demands huge variety ofconstruction projects, reinforced concrete structure is the main stream of the structurein the construction market of China,it occupys the entire building market share ofabout60%, and in the next ten to twenty years, construction of reinforced concretestructure will remain the mainstream of the construction market, so study on thereinforced concrete structure’s carbon dioxide emissions is important.Theconstruction industry as a large carbon dioxide emissions, especially reinforcedconcrete structure is generated a lot of carbon dioxide, which makes the research onreinforced concrete structure carbon dioxide is more necessary and urgent, the maincontents are as following:1.Reinforced concrete structure source of carbon dioxide emissions can bedivided into two aspects, one is construction site mechanical equipment, lighting andother energy-consuming carbon dioxide, the second is the generated using a variety ofbuilding materials, that is the indirect carbon dioxide emissions.2.Studied on carbon dioxide emission factor of major energy and constructionmaterials,in particular, maked a detailed analysis on some of the commonly usedmortar,concrete,it provides a method and perspective to calculate carbon dioxideemission factors of similar materials.3.Built the carbon dioxide emissions estimation model of reinforced concrete,this model is composed of two parts, direct and indirect carbon dioxideemissions,through the model we can calculate the total carbon dioxide emissions andthe proportion of each part.4. Calculate the different structural part’s carbon dioxide emissions through thedecomposition of reinforced concrete structures, identify the share of each part in totalcarbon dioxide emission.
