17、 Carbon Emissions affect Concrete structures? What is carbonation Carbonation is the formation of calcium carbonate (CaCO3) by a chemical reaction in the concrete. The creation of calcium carbonate requires three equally important substances: carbon dioxide (CO2), calcium phases (Ca), and water (H2O
18、). Carbon dioxide (CO2) is present in the surrounding air, calcium phases (mainly Ca(OH)2 and CSH) are present in the concrete, and water (H2O) is present in the pores of the concrete.茫灿寄敷瘤娩晋辽改朝窄济悲袁秧镊遭琵蟹晦消文窍店肿宿词蚜提冒搂臂How do Carbon Emissions affect Concrete structures of ChinaHow do Carbon Emissions a
19、ffect Concrete structures of ChinaHow do Carbon Emissions affect Concrete structures? The first reaction is in the pores where carbon dioxide (CO2) and water (H2O) react to form carbonic acid (H2CO3): CO2 + H2O H2CO3The carbonic acid then reacts with the calcium phases:H2CO3 + Ca(OH)2 CaCO3 + 2H2OOn
20、ce the Ca(OH)2 has converted and is missing from the cement paste, hydrated CSH (Calcium Silicate Hydrate - CaOSiO2H2O) will liberate CaO which will then also carbonate:H2CO3 + CaO CaCO3 + H2O孔休浪赛成君诀卧碍豆凋贤页涵同枫辕注诵拘帚漆柴阻赠犊躁糜峡洗吠果How do Carbon Emissions affect Concrete structures of ChinaHow do Carbon Emi
