The construction industry is an important source of greenhouse gas emissions, with cement production accounting for approximately 7% of global carbon emissions, of which 95% come from limestone calcination.
Traditional strategies focus on using auxiliary cementitious materials to replace some of the clinker in order to reduce carbon emissions per unit volume of concrete; The performance strategy reduces the amount of structural materials used by using high-strength concrete.
However, the carbon emissions during the production stage of high-strength concrete are higher, and its comprehensive carbon footprint needs to be evaluated specifically based on the type of building.
