건설현장의 CO2 배출 저감형 콘크리트 조달에 관한 사례분석

Abstract

The purpose of this study is to conduct a case study for procurement of CO2 emissions reduction concrete in the construction site. For this purpose, mix-proportion and energy consumption for ready mixed concrete were collected from 27 ready mixed concrete manufacturing plant in Korea using on-line questionnaire, visiting, telephone conversation and so on. And Concrete CO2 emission assessment was conducted observing Life Cycle Assessment method defined by ISO 14040 series with mix-proportion and energy consumption. With this, CO2 emission characteristic was analyzed dividing into the group such as compressive strength, admixture, plant region using the result of assessment. Furthermore, comparison analysis of real CO2 emission of a concrete plant and the minimum CO2 emission following was conducted.
