Special Issue Information

Dear Colleagues,

This Special Issue, "Concrete and Climate: Engineering Low-Carbon Solutions for the Building Sector", emphasizes engineering innovation and environmental sustainability. Portland cement, a key constituent in concrete, emits 8% of the world’s CO2. This makes lower-carbon concrete a worldwide priority and a scientific challenge. In response, this collection presents groundbreaking research on concrete formulations and methods to reduce carbon emissions.

This Special Issue discusses advances in calcined clays, slag, and fly ash, which reduce concrete's clinker factor. It also includes case studies of these technologies in real-world construction projects, proving their practicality and urban sustainability benefits. Green concrete's lifetime analysis reveals its long-term environmental benefits over traditional materials.

This Special Issue promotes sustainable construction worldwide by encouraging transdisciplinary

interaction between scholars, practitioners, and policymakers. It promotes cutting-edge research and collaboration to reimagine concrete as a material that benefits our planet.

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. Applied Sciences 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 2400 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.

This study aims to incorporate building and demolition waste, including lime and crushed granite, as partial alternatives for cement and fine aggregates, respectively, and to devise a plan to reduce their environmental effect resulting from their extensive prevalence in substantial amounts. The use of lime in paste, mortar, and concrete has become a common practice to regulate the environment, save resources, and improve performance in various settings. The first stage of this study investigated the effects of replacing different proportions (0%, 15%, 25%, 35%, and 50%) of lime powder with cement on the physical and mechanical properties of mortar specimens over 7, 28, and 90 days. The next phase of the research examined the impacts of substituting varying quantities (ranging from 10% to 100%) of granite powder in 15 different mixes, while keeping a consistent water-to-binder ratio of 0.45. The last part of the study consisted of an examination of data from previous research on cement mortar and lime-modified cement mortar. This included testing on flowability, standard consistency, setting time, flexural strength, and compressive strength. The acquired data underwent a statistical analysis, which resulted in the development of equations that may predict the mechanical characteristics of changed cement mortar mixes. These equations also highlight the impact of certain physical qualities on compressive and flexural strength. Full article
