Special Issue Information

Dear Colleagues,

Heritage Constructions are nowadays recognized as important assets, both for cultural and economic motives.

To preserve the material and immaterial values of Heritage Constructions, conservation actions may be needed, that do not destroy the original features and contribute for the protection and restoration of the old building or structure.

The materials used for those actions should be effective and durable, but also compatible with the old elements, in order to avoid secondary damage and loss of original value. They should also be sustainable materials and allow for sustainable, minimal interventions, considering that the reduction of the carbon footprint is nowadays an obligation for the construction and rehabilitation industry as a whole.

For such materials, with diverse functions and complex requirements, sometimes subjected to new actions, such as pollution and sudden hazards, innovation is needed.

The aim of this Special Issue is to gather knowledge about innovative and sustainable materials that can adequately contribute to the preservation, protection, and reinforcement of Heritage Constructions, without damage or destruction of material or immaterial values.

The following themes may be addressed:

  • Characterization and assessment of serviceability of innovative products, or systems for preservation, protection, or reinforcement of Heritage Constructions.
  • Characterization of innovative products or systems to improve the performance of Heritage Constructions in certain aspects related to sustainability, health or safety, such as thermal behaviour, acoustic behaviour or seismic performance.
  • Development of experimental methods and/or mathematical models for the assessment of innovative products or systems for application in conservation actions of Heritage Constructions.
  • Development and assessment of innovative products or systems to reduce the impact of climatic changes and intense sudden hazards in Heritage Constructions.
  • Impacts of the application of innovative products or systems for conservation in the sustainability of interventions on Heritage Constructions, considering the Life Cycle Assessment of the Constructions.

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. 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.

Characterization and Assessment of Performance of Innovative Lime Mortars for Conservation of Building Heritage: Paimogo’s Fort, a Case Study

Along the Portuguese coastline, several military fortifications were built with the intention to protect the territory from the constant military threat from the sea. These constructions have been subjected, during centuries, to a very aggressive environment; the renders, whose main function is the protection of walls, are particularly exposed to such actions. Nossa Senhora dos Anjos de Paimogo’s Fort, better known as the Paimogo’s Fort, is one of these fortifications, built in 1674 and classified of public interest since 1957. Within the scope of the “Coast Memory Fort” Project of EEA Grants Culture Programme 2014–2021, promoted by the Municipality of Lourinhã, repair mortars are being developed for the preservation of the Fort, considering the physical–mechanical and chemical characteristics of the pre-existing mortars and of the substrate, as well as the aggressive environmental conditions. In this work, several mortar compositions, compatible with the original mortars and designed to resist the aggressive environment, are briefly described and their main physical and mechanical characteristics are analysed and compared in successive ages. Different binder mixes were used, and a fine-tuning of the aggregate was carried out. Assessment of sequential wetting/drying cycles’ effect on the mortar’s behaviour is also presented. The laboratory results reveal that mortars with additions of 30% of quicklime present the best behaviour (with the lowest water absorption and highest strength). Moreover, the substitution of part of the siliceous sand by limestone aggregate, in general, increases the mortars’ mechanical strength; however, the drying occurs slower, which could compromise the durability of these mortars if a good balance is not achieved.

The repair and strengthening of historical masonry buildings is a fundamental aspect in the conservation of the built cultural heritage. Temporary shoring or strengthening are often used and, usually, involve the introduction of new metallic elements. The connection between the original substrate and the new elements must be analyzed carefully to prevent further damage to the building. This paper presents a study on the mechanical behavior of metal anchors applied to brick masonry walls. An experimental campaign is developed, and a series of pull-out tests are carried out on masonry walls built in a laboratory with natural hydraulic lime mortar and low mechanical strength bricks. Two groups of tests are conducted, namely, with the actuator in the direction of the anchor axis and with the actuator inclined with respect to the fastener axis. Moreover, two types of anchoring systems are used, namely, adhesive (chemical and cementitious grout) and mechanical anchors. The experimental results are compared to predictive analytical formulas available in the literature for estimation of the ultimate load capacity, according to the type of failure. From the comparison between experimental and analytical values, it is proven that the analytical formulation originally developed for concrete substrates cannot be directly extrapolated to brick masonry cases, and specific predictive formulas should be developed. The presented research can be used to select the most efficient anchoring system for strengthening and retrofitting of historical brick masonry structures. Full article
