Special Issue Information
Dear Colleagues,
Damages caused by expansive soils every year is estimated to be over $1 billion US in the USA, £150 million in the UK, and many billions of pounds worldwide. These damages are associated with failure to identify the extent of expansion in soils leading to the constant repair of damaged houses, roads and embankments due to the lack of a simplified and straightforward approach. Undoubtedly, the use of cement and lime in the mitigation of shrink–swell behaviour and improvement of the engineering properties of expansive clays cannot be overemphasized.
However, the environmental impact of the continuous emissions of toxic gases (carbon footprint) accompanying cement production, and with concerns regarding the built environment becoming increasingly urgent, there is a need for the development of novel eco-friendly materials for the stabilisation of expansive soils. Therefore, this Issue is aimed at bringing together original ideas on the application of waste materials and geopolymers in the stabilisation of expansive soils to evaluate micro–macro performance and create a better understanding on the behaviour of stabilized soils.
This Special Issue will focus on the development and application of sustainable soil stabilisation additives capable of improving the geo-mechanical properties of expansive soils, leading to the development of prediction models for soil CBR, stiffness, bearing capacity, permeability, swell potential, and unconfined compressive strength, including the micro-structural analysis of the stabilized soils. We welcome original research and review articles.

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. Geotechnics is an international peer-reviewed open access quarterly 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 1000 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.
