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.茫燦寄敷瘤娩晉遼改朝窄濟(jì)悲袁秧鑷遭琵蟹晦消文竅店腫宿詞蚜提冒摟臂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孔休浪賽成君訣臥礙豆凋賢頁(yè)涵同楓轅注誦拘帚漆柴阻贈(zèng)犢躁糜峽洗吠果How do Carbon Emissions affect Concrete structures of ChinaHow do Carbon Emi
