Recycled Aggregate and Recycled Aggregate Concrete

Dear Colleagues,

We are inviting submissions to a Special Issue on Recycled Aggregate and Recycled Aggregate Concrete.

Recycled aggregate (RA) includes recycled concrete aggregates produced from waste concrete and produced by processing source materials other than demolished masonry units. The use of RA in diverse construction areas such as granular materials in pavement and concrete structures will contribute to the carbon neutrality policy which has been a significant global issue.

Many researchers worldwide have tried to establish not only national standards but also international standards, mainly including general requirements for RA and recycled aggregate concretes (RACs). RAs can typically be classified into classes 1, 2 or 3 according to physical requirements, chemical requirements, and durability requirements. All the accumulated data from each paper in this Special Issue will help to upgrade the existing national standards or generate new international standards. Interest in the quality control and long-term performance of RAC structures is also growing.    

The aim of this Special Issue is to compile papers describing the recent scientific progress on the use of RA and supplementary cementitious materials (SCMs), nano-materials, and fibers which can compensate for the drawback of RAC. Proposals of new mix-proportioning methods considering attached mortars or old cement pastes from RAs in order to improve the mechanical strength properties and durability of RAC are welcome. We also encourage the submission of papers considering the use of RAs with SCMs in RAC applications which eventually reduce the carbon dioxide emissions associated with cement concrete construction (currently responsible for as much as 8% of human carbon dioxide emissions). Thus, any studies related to the reduction of carbon dioxide emissions as a result of using RAC are more than welcome.

In this Special Issue, we invite submissions exploring cutting-edge research and recent advances in the fields of RA and RAC. Both experimental and field studies are welcome, as are comprehensive review and survey papers.

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.
