Structural and Functional Performance of Geopolymer Materials

Dear Colleagues,

Geopolymers are amorphous ceramic materials obtained from the alkaline activation of aluminosilicates including those from wastes, such as mining waste, coal fly, and bottom ash, granulated blast furnace slag, water purification sludge, and so on.

In terms of applications as cement and concrete materials, they can reduce energy consumption during production, emission of greenhouse gases, and environmental impacts. These characteristics, combined with high early-age strength and fast hardness characteristics, allow considering these materials as a promising “green” alternative to ordinary Portland cement-based materials.

Geopolymer concrete can find application in building, construction, repair, restoring, marine construction, pavement base materials, 3D printing, fire-resistant and high-temperature materials, thermal and acoustic insulation. Moreover, they can be used in the construction industry to produce precast materials or in the coating of cement structures for the rehabilitation of compromised structures, flame inertization, and improvement of resistance to acids and water. Special applications include the immobilization of heavy metal pollution, pH regulator materials, catalysts, conductive materials for moisture sensor applications, and thermal storage.

Functional applications, such as fire prevention, isolation, heat preservation, and adsorption of harmful ions, can be used for buildings in special fields, such as fire prevention buildings, insulation walls, biomaterials, and, nuclear power plants can 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 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 250 words) can be sent to the Editorial Office for assessment.

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.
