“…Catalysts should be used at a limited scale. Methods used in biology, organisms and biological enzymes capture and store CO 2 and convert it into compounds such as glucose, carboxylic acids, and carbonates [9,70,71].

“…Cement emits approximately 0.79 tons of CO 2 per ton, according to a study by [6,7]. Approximately 5-9% of the global CO 2 emissions are attributed to the concrete industry [6,7,[9][10][11][12][13]. There is a rapid increase in this percentage mostly due to an increase in cement production and a decrease in emission reductions [6,14].…”

Concrete is one of the most commonly used engineering materials in the world. Carbonation of cement-based materials balances the CO2 emissions from the cement industry, which means that carbon neutrality in the cement industry can be achieved by the carbon sequestration ability of cement-based materials. Carbon dioxide is a symmetrical molecule and is difficult to separate. This work introduces the important significance of CO2 absorption by using cement-based materials, and summarizes the basic characteristics of carbonation of concrete, including the affected factors, mathematical modeling carbonization, and the method for detecting carbonation. From the perspective of carbon sequestration, it mainly goes through carbon capture and carbon storage. As the first stage of carbon sequestration, carbon capture is the premise of carbon sequestration and determines the maximum amount of carbon sequestration. Carbon sequestration with carbonization reaction as the main way has been studied a lot, but there is little attention to carbon capture performance. As an effective way to enhance the carbon sequestration capacity of cement-based materials, increasing the total amount of carbon sequestration can become a considerably important research direction.

In this text, a method to use CO 2 for the treatment of calcareous sand is presented. Carbon dioxide solidi cation-bacteria (Streptomyces micro avus) was obtained by screening and applied to the mechanical strengthening of calcareous sand through a microbial mineralization/carbonization process. Experiments in both liquid phase and sand were carried out. The optimal mass ratio of carbon dioxide solidi cation-bacteria to calcium oxide was found to be 2:1. The optimal dosage of bacterial powder was 30% of the total dry sand mass. Using the optimal recipe, the average uniaxial compressive strength of treated sand columns was 3.67 MPa and the average permeability coe cient was 4.90×10 -3 cm/s. Compared with the other microbial induced carbonate precipitation (MICP) approaches, the proposed method does not release harmful by-products such as ammonia. The chemical composition and microstructure of the treated calcareous sand were characterized by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results showed that the CO 2 carbonized product contained mainly calcite.
