The effect of temperature on corn straw ash production as supplementary cementitious material

Abstract

The civil construction sector is growing, which is of great socioeconomic importance. However, this increase has consequences that are already the focus of studies for many researchers. One of the main materials used in civil construction, cement, is responsible for a significant amount of carbon dioxide (CO2) emissions. Cement production alone has been responsible for approximately 8% of global CO2 emissions, primarily due to its high level of embodied carbon in cement factories (Blois; Lay-Ekuakille, 2021; Cadavid-Giraldo; Velez-Gallego; Restrepo-Boland, 2020 e Un Environment and International Energy Agency, 2017). Most of the CO2 emissions come from burning the clinker used to produce this filler, along with the significant energy consumption required for this process. Cement factories, in addition to this, are responsible for the rapid consumption and depletion of limited resources.
