Special Issue "Advances in Cement-Based Materials: Mechanical Behavior, Rheology, and Radiology"
Deadline for manuscript submissions: closed (10 August 2023) | Viewed by 23240
During the last 100 years, humanity has witnessed an outstanding change in social and cultural models, in many cases brought by advances in science and technology. For decades, however, the effects of energy and raw material consumption have been devastating to the environment. Moreover, the model of industrialization and development used generates high levels of pollution and the production of many industrial by-products, which end up in large landfills.
The field of building materials is no exception in this respect. Concrete is the most widely used artificial material in the world and its use is closely associated with improving the quality of life. However, the manufacture of Portland cement is a highly costly process from the energy and environmental point of view, so the scientific community has set itself challenges and guidelines to follow in order to curb this situation and move towards a circular economy and sustainable development. And this is being achieved through the use of supplementary cementitious materials, among which industrial waste or by-products stand out, or also through the use of non-conventional aggregates, such as recycled concrete aggregates. The development of new cementitious materials, exempt or with low amounts of cement, such as alkali-activated cements, hybrid cements or calcined clays containing cements represent also an important line of research.
However, the use of these materials reduces, in many cases, mechanical performance and affects the rheology of the final material. Furthermore, it must also be taken into account that the raw materials used in various industries, with a certain natural radioactivity, give rise after industrial processing to industrial wastes, with increased radioactivity (NORM). The use of these wastes in the manufacture of construction materials must ensure that not only do they meet technical requirements for resistance and durability, but also that they do not pose a risk to human health.
Therefore, we see that the development of new construction materials generates new challenges so that they are not only sustainable but also resistant materials, easy to implement and posing no health problems for living beings or pollution problems for the environment.
In this issue we want to compile works that give answers to some questions in this sense:
- How does the reuse of waste and industrial byproducts affect the mechanical performance and rheology of the final cementitious materials?
- How can these properties be improved?
- What amount and type of waste can be used in building materials without posing a radiological risk?
I invite you to contribute your works to this Special Issue that will undoubtedly represent an advance in knowledge.

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.
