Webthe CO2 uptake at low partial pressures correlates with the strength of sorbent-sorbate interactions. In contrast, each sorbent exhibits much lower CH4 uptake at 1.0 bar and … WebThe actual amount of carbon uptake will depend on a range of parameters including the resistance class, exposure conditions, thickness of the concrete element, recycling scenario and secondary use. A practical estimate of the global carbon sink provided by all concrete is 25% of the process CO2 emissions released during cement production.
