Partial replacement of cement and fine aggregate in mortar material by using carbon sequestration technique

Abstract

Carbon sequestration, also termed carbon dioxide removal, is the long-term process of removing, capturing, and storing carbon dioxide with the purpose of reducing or reversing atmospheric CO2 pollution and mitigating or reversing global warming (CDR). Cement, the primary component of concrete, has been used since ancient times, and as the world becomes more advanced technologically, the building sector will emit more CO2 emissions. There are two stages in the process of bond formation, and both of them release carbon dioxide. The first is the formation of oxides from carbonates during the making of clinker, the main ingredient in concrete. Many studies have shown that this kind of process discharge is responsible for around 5 percent of all CO2 emissions from human activity. In addition to vehicles, the combustion of carbon dioxide for heat is a significant contributor to air pollution. This happens if a lot of fossil fuels are burnt to produce a lot of energy. Second, we factor in the quantity of energy needed to heat the raw materials. This means that up to 8% of worldwide CO2 emissions may originate from the cement sector.
