25 Ιουν 2024 · Approximately 10 % of global anthropogenic CO 2 emissions arise from the cement and concrete industry driven by urban expansion and a constant need for infrastructure renewal. Reusing waste CO 2 to make new construction materials produces circular carbon flows and constitutes a key step toward a carbon-negative economy.
1 Απρ 2023 · Given the widespread use of concrete as the construction material of choice, achieving sustainable development goals in the civil infrastructure sector directly relies on reducing the concrete’s carbon footprint. For this purpose, a variety of innovative carbon sequestration and storage solutions have been introduced to date.
1 Δεκ 2020 · In order for the concrete industry to achieve net-zero carbon dioxide emission by 2050, there is an imminent need to ensure significant changes are implemented for the materials and processes used to produced concrete.
26 Ιουν 2024 · Cement is a key constituent of concrete and offers a large sequestration potential of carbon dioxide (CO 2). However, current concrete carbonation approaches are hindered by low CO 2 capture...
