Special Issue Information
Dear Colleagues,
The cement industry accounts for 6–8% of the world's carbon dioxide (CO2) emissions. To achieve carbon neutrality, many technologies have been increasingly developed to reduce CO2 emissions from cement-based materials and structures, including CO2 capture from cement factories, the use of waste in cement and concrete production, a decrease in the clinker ratio (e.g., blended cement), clinker-free cement (alkali-activated materials, geopolymer, etc.), and CO2 curing or mixing of concrete, etc. Self-compacting concrete and 3D-printed concrete may reduce the environmental burden (EB) in the construction stage of concrete; high-performance concrete (HPC) may reduce the EB in the life cycle of concrete structures by reducing a component’s size and increasing the life span; however, the processes of CO2 capture/curing/mixing, recycled material production, the operation of 3D printing equipment, and the production of admixtures used in HPCs also emit CO2. Therefore, an environmental assessment needs to be conducted for the life span of materials and structures.
The use of recycled materials does not only reduce carbon emissions, but also saves natural resources, landfill sites, etc. Therefore, a comprehensive life cycle assessment (LCA) is required for multi-EB items. Additionally, the LCA not only quantifies the EB, but also allows for a comparison of EBs of different materials and structures. Therefore, the methodologies for the integration of different EBs, and for the comparison of EBs between materials or structures with different technical properties, are also important issues.
The presented Special Issue concerns the publication of an LCA of cement-based materials and structures using alternative raw materials or new production/construction techniques. It will cover, but will not be limited to, the following topics: LCAs, life cycle impact assessments (LCIAs), integrated assessment methodologies, energy consumption analyses, environmental performance, computer-aided LCA tools, external or social cost calculations, environmental efficiency, building LCAs, and environmental benefit evaluations of waste utilization.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.
