Carbon Capture, Utilization and Storage Technologies of Cement-Based Materials

Dear Colleagues,

Under the global carbon neutrality mandate, the construction industry—a major carbon emitter—faces urgent demands to decarbonize traditional cement production. Cement manufacturing has become a focal point for sustainable building material research. Recent advancements in CO₂ capture, utilization, and storage (CCUS) technologies integrated with cement-based materials offer a potential pathway to transition from "carbon source" to "carbon sink," attracting significant attention from both academia and industry. This Special Issue seeks cutting-edge research on the full-chain innovation of CO₂ "capture–conversion–storage" in cement-based materials, driving low-carbon transformation from production to application. Key topics include, but are not limited to, the following:

1. Low-Carbon Binder Design: Novel low-calcium cements, carbon-activated industrial byproducts (e.g., steel slag, fly ash, etc.) as supplementary cementitious materials, and alkali-activated materials.
2. Carbonation Curing: Reaction mechanisms, process optimization, and impacts on concrete durability.
3. Carbon-Negative Construction Materials: CO₂ permanent sequestration (e.g., carbonated aggregates, precast elements, etc.) and life cycle assessment.
4. Scalable Implementation: Industrial-scale CCU–cement integration, carbon trading mechanisms, and cost–benefit analysis.
5. Multiscale Characterization: In situ monitoring of CO₂–material interactions and microstructural control strategies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
