Assessment of CO2 Capture in FA/GGBS-Blended Cement Systems: From Cement Paste to Commercial Products

Buildings, Год журнала: 2024, Номер 14(1), С. 154 - 154

Опубликована: Янв. 8, 2024

The cement industry’s intricate production process, including kiln heating and fossil fuel use, contributes 5–8% of global CO2 emissions, marking it as a significant carbon emitter in construction. This study focuses on quantifying capture potential blended systems through the utilisation phenolphthalein thermalgravimetric methodologies. Its primary objective is to assess absorption capacity these systems’ pastes. Initial evaluation involves calculating within paste, subsequently extended estimate content resultant concrete products. findings indicate that incorporating ground granulated blast-furnace slag (GGBS) or an ettringite-based expansive agent did not notably elevate carbonation depth, irrespective their fineness. Conversely, introduction fly ash (FA) augmented leading substantial 36.4% rise captured content. observed distinctions behaviour primarily stem from variances pore structure, attributable distinct hydration characteristics between GGBS FA. Thermal analysis confirms increased stabilisation FA blends, highlighting crucial influence material composition emission reduction. Incorporating both diminishes binder constituting almost half PC-concrete emissions. Initially, 60% shows lower emissions than 50% FA, but when considering capture, this dynamic significantly changes, emphasising additives patterns. underscores complexity evaluating carbonation-induced cementitious systems.
