Special Issue Information

Dear Colleagues,

The sustainability of the construction field involves numerous aspects related to the durability and the contamination of building materials as well as the life cycle and the environmental impacts. The reuse/recycling of materials in the civil engineering and building sectors became an important concern in recent decades. The enormous production of inert material waste during construction, such as for instance tunnel break aggregates or excavation as well as the demolition of built infrastructures triggers new finding and possibilities to recycle the mass. This is particularly needed in the lack or reduction of disposal spaces. Many type of inert waste are considered in the building sector, such as recycled concrete aggregates, milled asphalt granulates, excavation or fluvial material, quarry debris, cementitious dusts, various type of ashes or alternative cementitious binder in substitution of Portland cement.

The issue addresses researchers as well as construction companies, engineers, architects, technical managers and specialists that deal with durability and recycled or re-used construction materials. The scope would be to gather the actual and most recent developments and knowledge related to the recycling and the mechanical as well as the durability properties of these new material mixes.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Recycled/reused construction materials in the infrastructure and buildings
  • Mechanical performance of the new recycled/reused materials
  • Durability of the new recycled/reused materials
  • Alternative cementitious binders
  • Recycled materials in the pavement sector
  • Recycled metals, asphalt, ceramics, plastics and wood in the construction field
  • Waste management within the construction materials
  • Supplementary cementitious materials
  • Life cycle management

We look forward to receiving your contributions.

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. Sustainability 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.

In Brazil, with the ban on the production, sale, and use of chrysotile asbestos, the sector’s industry opted to replace asbestos with CRFS Technology—Cement Reinforced with Synthetic Wire (fiber cement); that is, another product to be disposed of in landfills. This work aimed to determine a composite based on clay, fiber cement powder, and cement that meets the technical specifications of Brazilian soil–cement application standards to contribute to a more sustainable treatment of the future disposal of fiber cement products. With the characterization analysis of the materials, we identified that the clay granulometry is heterogeneous and distributed from 0.1 µm to 25 µm. In comparison, 75% of the fiber cement powder has grains greater than 10 µm. For clay, the liquidity limit is 39.67%, the plasticity limit is 25.01%, and the plasticity index is 14.66%. In the semiquantitative chemical analysis, silicon oxide (SiO2) and calcium oxide (CaO) stood out as the main oxides found, reflected in the mineralogy as quartz and calcium silicate. Therefore, we identified the percentage of organic matter in clay at 2%, using the result of the thermogravimetric analysis. The results described met the normative parameters foreseen for soil–cement applications. That said, the technological characterization was carried out by tests of linear retraction, water absorption, and simple mechanical compression on the specimens made under an axial pressure of 31.2 Mpa in the formulations defined in this work. The formulations with 10% cement and 20% and 30% fiber cement powder are suitable for use in soil–cement bricks, as they have volumetric shrinkage percentages from 2% to 2.5%, water absorption ranging from 18.66% to 19.39%, and simple compressions from 4.25 Mpa to 6.88 Mpa, meeting the requirements of Brazilian standards for soil–cement applications. It is concluded that the results showed that it is possible to produce soil–cement bricks with passive fiber cement products converted into powder, avoiding improper disposal and unwanted environmental impacts.
