Co2 emission analysis of metakaolin and alccofine replaced concrete in m40 grade concrete

Abstract

Abstract Among the largest CO2 emission industries, the cement industry is ranked at 2nd place. Large volume of CO2 is emitted at the clinker production, which is a cement manufacturing intermediate product. Countries around the world were having difficulty reducing atmospheric emissions of greenhouse gases (GHG). Concrete is still being used more and more as the nation's infrastructure advances. The amount of CO2 emitted by concrete can be decreased by using less cement or substituting other materials for cement. In this study the CO2 emission analysis is made on M40 grade, which is metakaolin (MK) and alccofine (AL) replaced concrete and is compared with the conventional concrete. The optimum cement replacement of MK and AL is 10% in the production of M40 grade concrete. The LCA (life cycle analysis) is made for the concrete specimens and the results were interpreted to know which concrete sample emits less and more carbon dioxide. These results could also help in identify the major cause for the CO2 emission and it can be used for the further research purposes..
