Special Issue Information

Dear Colleagues,

The building and construction industry is responsible for massive consumption of natural resources, along with significantly high embodied energy and greenhouse gas emissions. This Special Issue focuses on the development of cement-based materials and pertinent technologies which will advance the sustainability of the building and construction industry. The topics shall highlight not only the advances in material science and engineering that contribute to the development of future climate-smart construction materials, but also the potential application of life-cycle sustainability assessment of products and structures that incorporate cement. Contributions from academic researchers and practitioners in the form of original research papers, case reports, short communications and review papers are encouraged to stimulate discussion on sustainable materials design from conception and application to structures, as well as their evaluation throughout their complete life cycle. This Special Issue thus aims to present a collection of articles on topics including but not limited to the following:

  • Synthesis of novel cementitious materials (e.g., lightweight geopolymer/concrete, fiber-reinforced alkali-activated material, etc).
  • Characterization techniques and modeling with advanced microscopy and spectroscopic techniques, X-ray microtomography, among others.
  • Novel experimental techniques for the testing of materials, products, and structures and their applications.
  • Novel diagnosis, retrofitting, and repair techniques for concrete structures.
  • Integrated visualization as well as computational and systems engineering tools to measure and communicate the sustainability attributes of products and structures containing cement (multi-criteria analysis, life-cycle analysis, expert system, BIM, etc.).

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. Buildings is an international peer-reviewed open access monthly 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.

Abstract
This study explored self-healing in geopolymer mortar cured at ambient temperature using polypropylene fibers and bacterial co-cultures of Bacillus subtilis and Bacillus megaterium. Damage degree, compressive strength, ultrasonic pulse velocity (UPV), strength-regain percentage, and self-healing percentage were evaluated. A full factorial design [...] Read more.
This study explored self-healing in geopolymer mortar cured at ambient temperature using polypropylene fibers and bacterial co-cultures of Bacillus subtilis and Bacillus megaterium. Damage degree, compressive strength, ultrasonic pulse velocity (UPV), strength-regain percentage, and self-healing percentage were evaluated. A full factorial design was used, which resulted in an eight-run complete factorial design with four levels in the first factor (polypropylene content: 0%, 0.25%, 0.5%, and 0.75%) and two levels in the second factor (bacteria concentration: 0 (without) and 1 (with)). The results indicate that increasing the polypropylene fiber content enhanced strength regains up to 199.97% with 0.75% fibers and bacteria. The bacteria alone improved strength-regain percentages by 11.22% through mineral precipitation. The analysis of variance (ANOVA) showed no interaction between fibers and bacteria, but both independently improved the compressive strength. Only bacterial samples exhibited positive self-healing, ranging from 16.77 to 147.18%. The analysis using a scanning electron microscope with energy dispersive X-ray (SEM-EDX) and X-ray fluorescence (XRF) also revealed greater calcite crystal formation in bacterial samples, increasing the strength-regain and self-healing percentages. The results demonstrate that polypropylene fibers and bacteria cultures could substantially enhance the strength, durability, and self-healing percentage of geopolymer mortars. The findings present the potential of a bio-based self-healing approach for sustainable construction and repair materials. Full article

The work described in this paper assays in detail the improvements in the prominent features of cement mortar cube (CMC) specimens by blending them with 53 grade ordinary Portland cement (OPC), ultrafine slag (UFS), river sand, and graphene oxide (GO). These combinations were evaluated to determine which mixture best provided impressive strength attributes to the mortar. GO, in four different quantities, was explored as a blend (0.01%, 0.02%, 0.03%, and 0.04%). The combination with 10% UFS and 0.03% GO-infused CMCs exhibited improved compressive strength compared to all samples after being cured for three, seven, and twenty-eight days. The higher performance of the 10% UFS and 0.03% GO mortar cubes was further endorsed by durability and microstructural tests, such as water absorption, sorptivity, ultrasonic pulse velocity, rapid chloride permeability, electric resistivity, carbonation, FE-SEM/EDX, and XRD. From all the results, it was evident that the mortar containing 10% UFS and 0.03% GO has the best properties for shielding it from deterioration and may be employed as an augmenting structural material in the construction sector.
