In total three types of experimental procedures are presented. Tensile experiments, 3 PT bending tests, and finally, 4 PT bending tests of large-scale beams are conducted. The research highlights the potential of HC3DP in architectural applications, particularly in the construction of high-performance, site-specific facades. The findings underscore the importance of planning and design for the 3D printing process, emphasizing the critical role of printing direction in determining the structural behavior and performance of 3D printed facade elements. Additionally, the paper presents a theoretical model for calculating for the maximum spanning distance of 3D printed facades, based on the results obtained from the experiments presented. The results demonstrate that HC3DP is a promising technology for facade construction, enabling the fabrication of aesthetically unique and material efficient 3DP facades with a better structural capacity then comparable conventional ME methods.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"23 ","pages":"Article 100703"},"PeriodicalIF":6.2,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incorporation of fine glass powder (<1 μm) significantly enhances glass network reactivity by increasing the surface area in contact with the alkaline solution. This promotes the dissolution of glass constituents, leading to their subsequent polymerization. Following this process, the material undergoes low-temperature curing at 40 °C, aiding consolidation and stabilization. The resulting porous structure shows excellent performance in copper removal from aqueous media. While adsorption of copper is strongly influenced by the pH of the solution, the adsorption capacity can be adjusted through surface treatment of the activated material. The developed borosilicate-based membranes treated in boiling water can remove between 92 % and 99 % of copper (II) at pH levels 2 and 5, respectively, whereas “raw” alkali-activated samples achieve up to 65 % copper (II) removal at pH 2.

Subsequently, an uncertainty analysis was conducted to evaluate the data quality of each inventory phase. The comparative analysis of environmental impacts, focusing on carbon emissions and energy demand, revealed that HIPR and HIR technologies offer substantial environmental benefits. Notably, M&F technology exhibited a wider uncertainty range, which is attributed to its greater reliance on secondary data sourced from public databases. In contrast, the HIR technology demonstrated the lowest uncertainty, suggesting a more reliable environmental impact assessment.

The use of AAMs as a low-carbon alternative to cement reduces environmental impact, while carpet waste fibers contribute to a circular economy by repurposing textile waste. Durability tests under severe rainfall revealed that the stabilized material retained 99 % of its compressive strength, while unstabilized rammed earth lost 28 %. Additionally, the stabilized material exhibited a fourfold increase in tensile strength. This method also significantly improved toughness and brittleness index, maintaining performance under harsh rainfall conditions. Microstructural analysis revealed improved bonding and densification, enhancing long-term durability.

Uniaxial compression DEM numerical simulations are used to evaluate the macroscopic mechanical responses and stress-strain relationships of PCs with various aggregate shapes. The results indicate that regular aggregate shapes can reduce void ratio and enhance load-bearing capacity. While the effect of aggregate shape on the ascending branch of the normalized stress-strain curve is limited, increased aggregate shape irregularity results in a steeper descending branch.
