Coal gangue (CG) is one of the most frequent solid wastes in world, and it poses a severe hazard to both human society natural ecosystems. In light progressive increase environmental awareness unavoidable trend requirements sustainable development plan, how efficiently use these vast quantities CG has become an important subject China. Concrete aggregate, which can not only solve pollution but also compensate for scarcity gravel sand resources, cost-effective eco-friendly way utilize resources accordance with strategic green development. However, deal preparation high-quality aggregate needs be targeted research; blindly using concrete may bring some safety hazards. This requires that based on source, distribution, storage, chemical composition, mineral composition problems utilization process, efforts are made open up key routes utilization, provide theoretical guidance high-value environmentally friendly CG. paper summarizes characteristics its impact performance, discusses technical means improve performance concrete, analyzes if current application problem still exists, view gradually realize low-energy consumption bulk utilization. The popularization will accelerate solution brings, certain extent alleviate situation supply insufficient meet demand; today’s research economic significance.

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.
