Shotcrete/Sprayed Concrete Technology

Dear Colleagues,

Shotcrete is a kind of special civil-engineering technology. Shotcrete material is transported with the introduction of compressed air through the pipeline and then sprayed on the sprayed surface. Because of its high construction efficiency and good sealing structure, it is widely used in underground engineering, slope support, road traffic, and other fields. However, in the current shotcrete process, some problems such as the flow characteristics of cross-scale particles in pipeline pumping, the development of shotcrete materials and equipment, the process of shotcrete, the concrete deterioration mechanism in special environments such as high temperature and high pressure, etc., restrict the development of shotcrete towards a more efficient and safer direction. Therefore, the exchange and discussion of shotcrete is helpful for the safe and efficient development of underground space and ground buildings.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: shotcrete, ultra-high-performance concrete, concrete deterioration mechanisms in special environments, air-entrained concrete, thin-layer shotcrete, 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. Materials 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 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.
