Special Issue Information

Dear Colleagues,

Many important building materials used in construction are porous, permeable and can absorb water under the action of capillary forces. Indeed, a wide diversity of materials such as mortar, stone, brick, tiles, plaster, concrete or adobe are included in this broad definition and, beyond sharing a porous microstructure, many suffer from similar degradation mechanisms and the required conservation actions or products do not differ greatly. Therefore, the special issue aims to gather original research work related to the conservation of historic porous building materials without overlooking the specificities of each material since it also intends to highlight that detailed condition assessments are essential before any conservation measure. Research concentrating on monitoring of degradation phenomena, the durability and retreatment of conservation treatments is welcome as these topics are understudied.

Suggested topics to be covered include, but are not limited to the following:

  • Novel materials and methods for cleaning and consolidation
  • Novel materials for protection against water-related degradation, biocolonization, graffiti or other threats
  • Design and evaluation of compatible repair materials and products
  • Studies on the effectiveness, compatibility, durability or retreatment of restoration actions or conservation treatments
  • Comparison of laboratory and in-situ testing methods for the validation of conservation treatments
  • The role of moisture transport on the durability of porous building materials
  • Studies on the degradation of historic porous building materials

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.

This work aims to reveal the recent research trends in the consolidation of stone-built heritage and discuss the advantages and drawbacks of the options and strategies followed by researchers over the last 10 years. Peer-reviewed articles were used to build a database and analyze the details of the stone samples (chemical nature, type of voids, and condition), treatment protocols (application methods and consolidation products), and testing methods to assess the strengthening results of the treatments. In addition, the reported increments in the mechanical properties were also examined to reveal the strengthening capabilities of recent consolidation treatments. The statistical treatment of the results allowed pinpointing the stone varieties that need more frequent consolidation actions (limestone, biocalcarenite, and sandstone) and the aspects that make them more difficult and riskier. Other tendencies were discussed, for example, the predominant use of sound samples over decayed samples (61% vs. 39%) or the predominant use of alkoxysilanes (~46%) over other families of consolidants (e.g., nanolime, ~21%). The current consolidation treatments were found to improve stone strength; however, the most problematic issue in state-of-the-art is the difficulty of identifying high-risk situations of over-consolidation or poor distribution in depth because of either the lack of testing or limitations of the various assessment techniques.
