Synthesis of zeolite-carbon composites using high-carbon fly ash and their adsorption abilities towards petroleum substances

Lidia Bandura et al.

Summary: High-carbon fly ash was used to produce zeolite-carbon composites, which exhibited excellent adsorption performance for petroleum substances removal. The composites showed well-defined zeolite crystals formed onto carbonaceous surface and higher specific surface area compared to fly ash, leading to a higher sorption capacity towards oils.

Belite cements and their activation

Ana Cuesta et al.

Summary: Belite cements, or BCs, are low heat cements containing belite, alite, and calcium aluminates. They produce high amounts of C-S-H gel and have good durability properties, but their early-age strength development is not as competitive as that of Portland cements. To improve early-age strength development, research on activation using chemical, physical, and admixture approaches is a priority.

Municipal solid waste incineration fly ash to produce eco-friendly binders for sustainable building construction

Cristina Marieta et al.

Summary: The study aims to explore the feasibility of using municipal solid waste incinerator (MSWI) fly ash as raw material for sintering belite cements. Results show that MSWI fly ashes have suitable composition, but proper pre-treatment is required to eliminate chloride and heavy metal traces, and to enhance pozzolanic activity. Additionally, the addition of vitreous silica in proper proportions is necessary.

Effects of the Curing Conditions on the Carbonation Curing Efficiency of Ordinary Portland Cement and a Belite-Rich Cement Mortar

Hyeju Kim et al.

Summary: The study found that providing additional moisture during carbonation curing lowers curing efficiency. The hydration products of cement paste are mainly affected by the depth at which the specimen was immersed in the liquid, rather than the type of liquid used.

Influence of metallic precursors in the mineralogy and reactivity of belite cement clinkers obtained by flame spray pyrolysis

Natalia Betancur-Granados et al.

Summary: By utilizing different metallic precursors, the alternative process can produce cementitious materials with faster hydration rates. Compared to traditional cementitious materials, these new materials can complete the hydration process within 24 hours, demonstrating good hydraulic behavior.
