Special Issue Information

Dear Colleagues,

Currently, civil construction uses many natural resources, such as water, sand, among others, and these are becoming increasingly scarce as a result of population growth. Furthermore, cement production is highly polluting, responsible for a large portion of the emission of greenhouse gases. Thus, focusing on environmental issues, this special edition is dedicated to publishing original scientific research papers on new materials for civil construction with a focus on sustainability. These materials can be produced by using industrial waste, associated or not with technologies for their improvement, such as nanoparticles, polymers, among others. However, it is not limited to the use of waste, any new material or technology that reduces the need to extract natural products or extends their life time that, consequently, reduce the discarded volume are applicable. Methods, techniques, computer simulations that can be applied in the assessment of environmental impacts arising from the use or production of these materials can also be presented.

Thus, scientific research focusing on new materials or methods with concern for sustainability will be welcomed in this special edition.

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.

The production of commercially used cement-based bricks has significant environmental implications, necessitating the development of robust, environmentally friendly alternatives. This study assesses the strength and durability of soil bricks by utilizing an eco-friendly stabilizer, which includes lime and natural-fiber-derived staple fibers. Soil bricks, each sized 50 mm × 100 mm and featuring varying proportions of stabilizer and wood chips, were subjected to unconfined compression and bending strength tests, permeability assessments, steel ball/golf ball (SB/GB) evaluations, and wetting–drying tests. The results demonstrated that higher stabilizer ratios and lower wood chip ratios led to enhanced unconfined compressive strength. Additionally, repeated wetting–drying cycles reduced the strength by up to 63%, while the relative dynamic modulus of elasticity decreased by as much as 45% with increasing wetting–drying cycles. Notably, the eco-friendly stabilizer significantly improved soil shear strength, ultimately enhancing the durability of the soil bricks. Full article

The principles of the circular economy are the basic determinants of the sustainable development of road construction. This paper presents a field study with a new concept of asphalt pavement structure with ecologically oriented attributes, significantly reducing the asphalt pavement carbon footprint while achieving a level of long-term performance comparable or greater than that of conventional pavement structures. The sustainable pavement consists of the introduction of a BIO-additive that allows for the integration of higher percentage of reclaimed asphalt pavement (RAP) as an alternative to the traditional asphalt mixtures. In the sub-base the use of construction and demolition waste was adopted. The results were obtained from a full-sized test section of the road structure divided for reference and eco-innovative cases. Mechanistic analyses were performed for materials and pavement structure based on laboratory tests and on-site assessment. The new eco-design solution was subjected to a comprehensive LCA and LCCA analysis and summarised by SWOT assessment. Full article

Limestone calcined clay cement (LC3) has considerable potential for large-scale implementation. We investigated three selected kaolinitic clays at different locations in South Africa. LC3 mortars were compared to Portland cement mortar as control, particularly the hydration phase mineralogy/content, microstructure, compressive strength, and 3D void structure. The investigation indicated that similar pozzolanic oxide (SiO2 + Al2O3) could be obtained from calcined clay of varied kaolinite content. While kaolinite content improves the pozzolanic activity, consistency, and compressive strength of the mortar, the void refinement at the microscale depends on the degree of limestone filling/hydration. The hydration phase contents, microstructure, mineralogy, and porosity of the processed kaolinitic clays were determined to be adequate. However, it is noted that the intrinsic content of limestone (and gypsum) in commercially available Portland cement should be considered for equivalent clinker, limestone, and gypsum contents of 50%, 15%, and 5%, respectively.
