Special Issue Information

Dear Colleagues, 

In recent decades, higher performance and increased sustainability are the two major research trends in concrete technology. On the one hand, concrete materials for modern construction are expected to possess better mechanical behaviour, using either advanced binder technology or high-performance fibre reinforcement. On the other hand, tremendous interest has been attracted to greener concrete materials in order to reduce carbon emissions and mitigate the consumption of natural resources. Among the available achievements, geopolymers can typically be regarded as a green cementless binder, sourced from industrial/agricultural/urban wastes/by-products. The development of both high-performance and green geopolymer/cement concrete composites can be solid foundations to support modern urbanization and civilization.

This Special Issue aims to present the recent advances and new achievements on green or high-performance geopolymer/cement concrete composites for sustainable and resilient infrastructure. We welcome high-quality original research papers and state-of-the-art reviews dealing with, but not limited to, the following topics:

  • Geopolymer (alkali-activated) concrete and composites;
  • Cementitious composites;
  • High-performance geopolymer/cement composites;
  • Fibre-reinforced geopolymer/cement composites;
  • Nanotechnology in geopolymer/cement composites;
  • 3D printed geopolymer/cement concrete;
  • Fibre-reinforced polymers in construction;
  • Other low-carbon binder materials.

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. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

To investigate the influence of polypropylene–basalt hybrid fibers (PBHFCC) on the durability of ceramsite concrete, this study determined the appearance change, mass loss rate, relative dynamic elastic modulus, compressive strength and splitting tensile strength of ceramsite concrete with four kinds of hybrid fibers volume admixture under chloride erosion and dry–wet cycles. The results reveal that under this effect, the apparent damage of each group of specimens increased with the growth of the erosion time. The quality, compressive strength and splitting tensile strength of the specimens all increased gradually during the erosion age period of the first 72 d and gradually decreased after 72 d. The relative dynamic elastic modulus was similarly mutated in 48 d. When the hybrid fiber content of the specimens is 0.15 vol %, the enhancement effect of ceramsite concrete is better than that of the other three amounts. The relative dynamic elastic modulus value is used as a damage variable to establish the damage equation, and the damage evolution equation of PBHFCC considering the volume of hybrid fiber under chloride erosion and dry–wet cycle is derived. The conclusions can be used as a reference for the durability design and construction of PBHFCC. Full article
