Special Issue Information

Dear Colleagues,

The construction industry faces urgent challenges in reducing its environmental footprint while maintaining structural performance and durability; consequently, this Special Issue, “Advanced Composite Materials for Sustainable Construction”, seeks to explore innovative cement-based composites incorporating waste-derived and recycled materials to promote sustainable development. Contributions highlight cutting-edge research on the use of industrial byproducts (e.g., fly ash, slag, and recycled aggregates) and novel additives to enhance mechanical properties, durability, and eco-efficiency. Topics include microstructure optimization, low-carbon binders, life-cycle assessment, and scalable applications in modern construction. By bridging material science and civil engineering, this Special Issue aims to advance the understanding of sustainable composites, offering practical solutions for resource conservation and circular economy principles. Researchers and practitioners are invited to submit original studies and reviews that address these critical challenges, fostering the transition toward the deployment of greener high-performance construction materials.

Previous research on geopolymers has not fully established their porosity and its influence on the matrix structure, as well as its relevance to mechanical and durability properties, supporting the potential of this material as a sustainable alternative to traditional construction materials. In this study, three geopolymer mortar (GM) mixtures were prepared: the first was obtained with fly ash (FA) without mechanical grinding (GM_FA), the second with FA that required crushing and sieving through a #200 sieve (GM_FA_200), and the third was a GM with FA that required crushing and sieving through a #325 sieve (GM_FA_325). The main objective was to evaluate the porosity of the geopolymeric paste and the interfacial transition zone (ITZ) between the aggregate and the geopolymerization products. Due to the susceptibility of this area to develop higher porosity, which leads to reduced mechanical properties and durability, it has become a significant focus of investigation in materials such as concrete and mortar. These analyses were carried out using physical adsorption of gases (PAG), and a methodology for image analysis of GM microporosity was implemented using micrographs obtained from a scanning electron microscope (SEM) and processed with the NI Vision Assistant 8.6 software (VA). The results from both image analysis and physical adsorption demonstrated that the GM_FA_325 matrix exhibited 19% less porosity compared to the GM_FA matrix. The results confirmed that GMs are predominantly mesoporous. It was observed that GM_FA_325 has the lowest total porosity, resulting in a denser and more compact microstructure, which is a key factor in its mechanical performance and potential applications as an eco-friendly construction material for coatings and precast elements such as blocks, panels, and similar products. In addition, image analysis using VA is highlighted as an efficient, cost-effective, and complementary technique to PAG, enabling robust results and resource optimization. Full article
