Special Issue Information

Dear Colleagues,

Humanity is facing unprecedented challenges driven by climate change, with the building sector playing a critical role in global sustainability efforts.

Responsible for nearly a third of total energy consumption and a quarter of greenhouse gas emissions, this sector presents significant opportunities for decarbonization and innovation. This Special Issue explores innovative building solutions that address the urgent need to transition toward decarbonized and sustainable construction practices. By leveraging cutting-edge materials, advanced construction technologies, and energy-efficient design strategies, the contributions to this Special Issue highlight pathways to reduce embodied and operational carbon emissions in buildings, in meeting the objectives outlined by the recast of the Energy Performance of Buildings Directive (EPBD).

This Special Issue contributes to the growing body of knowledge aimed at transforming the construction industry into a driver of climate neutrality, offering actionable insights for policymakers, industry professionals, and researchers.

Topics of interest include the following:

  • Development of low-carbon construction materials and technologies for decarbonized building practices;
  • Integration of renewable energy systems into building designs;
  • Circular economy approaches in construction, focusing on material reuse, recycling, and waste reduction;
  • Digital tools and simulations for optimizing building energy performance and reducing greenhouse gas emissions.
  • reviews innovative building solutions.

The disposal of rice husk ash (RHA) in rice-producing regions poses critical environmental and public health challenges. However, RHA’s high amorphous silica content offers significant potential for soil stabilization, particularly in improving the mechanical properties of weak soils. This study investigates the shear strength of clay soil stabilized with rice husk ash (2%, 4%, 6%) and low cement dosages (2%, 4%, 6%) that incorporate layered subgrade systems (top, bottom, and dual-layer configurations). By optimizing rice husk ash incorporation with reduced cement content, this approach challenges conventional stabilization methods that rely heavily on cement. Sixteen soil-cement-RHA mixtures were evaluated through mechanical testing, supplemented by microstructural and elemental analyses using scanning electron microscopy and energy-dispersive X-ray spectroscopy. Results demonstrated substantial improvements in shear strength across all subgrade layers. The dual-layer system with 2% RHA 6% cement (2%RHA6%C) achieved the highest cohesive strength (115 kN/m2) and maximum deviatoric stress (446 kN/m2). These findings highlight the viability of RHA as a sustainable, low-cement soil stabilizer, offering dual benefits: effective waste valorization and enhanced geotechnical performance. This study advances sustainable ground engineering practices by introducing a resource-efficient novel building material and provides a framework for layered stabilization systems in clay soils. Future investigations will focus on a broader range of soil types and extend the application of this approach to other sustainable ground engineering practices. Full article

The literature on belitic cement reveals adequate properties for use in mortars: increased workability, greater strength, durability, and a significant reduction in the temperature of clinker synthesis. Therefore, this material has great potential for minimizing the negative environmental impact caused by the cement industry. The scarcity of natural resources has been a major problem, and the valorization of industrial waste could be an alternative in the production of belitic cement. The characterization of by-products has been investigated to improve cement and mortar performance. The presented systematic mapping of the literature aims to identify innovative studies and methods for using industrial waste incorporated into the production of belitic cement. Initially, 150 articles were identified and, after filtering by the inclusion and exclusion criteria, 65 articles were selected. Six different types of belitic cement were identified and diverse waste and formulations were used. The results indicated that 10.7% (7/65) of the studies analyzed the performance of belitic cement, 83% (54/65) used industrial waste in cement formulation, 15.3% (10/65) used belitic cement based on industrial waste in mortar composition, and 33.8% (22/65) reported that the sinthetization temperature of the clinkers was less than 1350 °C, revealing low energy production and low CO2 emissions during the sinthetization of clinkers.
