A Development on Assessment System of CO_2 Emission and Economical Efficiency in the Life Cycle of Concrete

The main reason of the earth global warming is CO_2 and the regulation about it in the whole world has been reinforced to reduce CO_2 emission. It is needed that we should reduce it in the process at the production of concrete generated much of CO_2emission as the primary material of construction industry recognized unfriendly environment industry. Based on a concrete, this study was constructed the Assessment system of CO_2 emission and economical efficiency in the life cycle of concrete to evaluate CO_2 emission generated in the stage of material production, transportation, manufacture using optimal design techniques. This study evaluates CO_2 emission and economical efficiency of ready-mixed concrete according to producing companies or standards,using the proposed program in this study, which is the assessment program of CO2 emission and economical efficiency in the life cycle of concrete(SUSB-CLAS). CO_2 emission basic unit and economical efficiency DB in various concrete types are constructed throughout this study and will be used for prediction of CO_2 emission and economical efficiency in concrete industry and for fundamental resource for reducing CO_2 emissions
