Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. They are important constituents of soil, and are among the most common and readily accessible of all of the materials encountered in construction operations. Most clay soils, particularly those containing active smectite minerals such as montmorillonite, are characterized as problematic, as their intrinsic mechanical features, for example, strength, bearing capacity and volume change, are often less than ideal for common geotechnical engineering applications. Clay soils are generally reactive to moisture variations, and their behaviour under loads consists of immediate and time-dependent deformations, that is, consolidation and creep, which present significant challenges for geotechnical engineering systems. Where exposed to seasonal environments, active clay minerals exhibit significant swell–shrink volume changes and desiccation-induced cracking, thereby bringing forth instability concerns to the overlying structures, and hence incurring large amounts of maintenance costs. Consequently, clay soils demand engineering solutions to alleviate the associated socio-economic impacts on human life. A leading solution to counteract such adversities is soil stabilisation, which includes any chemical, mechanical, biological, or combined practice of altering the soil fabric so as to meet the intended engineering criteria. This Special Issue aims to bring together corresponding original studies related to the identification, classification, characterisation, and stabilisation of clays and clay minerals for their effective use in geotechnical engineering projects. Fundamental constitutive modelling studies, analytical and numerical analyses, and experimental and field investigations will be considered.

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 papers will be 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. Minerals 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 1400 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.
