표면마감 조건에 따른 탄산화감소계수 및 CO2 흡수량 산정

Abstract

Emissions of CO2 occur during the production of cement manufacturing process. During the production of clinker, limestone is mainly calcium carbonate, is heated to produce lime and CO2 as a by-product. It has a major problem, CO2 uptake is not considered in concrete carbonation, just focus in CO2 emission. This study is to develop a simulation model for CO2 uptakes in concrete structures based on carbonation reduction coefficient considering finishing materials. CO2 uptakes unit of concrete cubic meter is calculated by CO2 emissions unit of concrete materials and usage of concrete materials in mix proportion. From the simulation result, CO2 uptake ratios is 2.04 percent in carbonation models of concrete structure during 40 years.
