In a significant advancement for sustainable construction practices, researchers have delved into the axial compressive behavior of glass fiber reinforced polymer (GFRP) tube confined seawater and sea sand concrete (SSC) columns. This innovative approach not only addresses pressing environmental concerns but also offers practical solutions to the construction industry’s ongoing material shortages.
The study, led by Jiansheng Cui from the Jiangsu Engineering Research Center for Intelligent Coastal Power Infrastructure, involved testing 12 groups of GFRP tube confined SSC short columns, comparing their performance against ordinary concrete columns. This comparative analysis revealed that the unique properties of SSC, when confined within GFRP tubes, can significantly enhance the structural integrity of concrete columns. “Our findings indicate that increasing the strength grade of concrete and the wall thickness of the GFRP tube can notably improve the ultimate bearing capacity of composite columns,” Cui stated, highlighting the dual benefits of sustainability and structural efficiency.
As the construction sector increasingly seeks to reduce its carbon footprint, the use of seawater and sea sand in concrete production emerges as a promising alternative. This method not only mitigates the environmental impact associated with traditional river sand extraction but also aligns with global efforts to combat climate change. The incorporation of fly ash into the concrete mix further enhances its performance, although the study cautions against excessive amounts, which can diminish strength.
The research also underscores the comparable performance of GFRP tube confined SSC columns to those made of conventional concrete, suggesting a seamless transition for builders looking to adopt more sustainable practices. “The compressive behavior of GFRP tube confined SSC columns is not very different from that of GFRP tube confined ordinary concrete columns,” Cui remarked, emphasizing the viability of this approach for future projects.
This groundbreaking research, published in “Advances in Civil Engineering,” offers a roadmap for the construction industry to embrace innovative materials that not only fulfill structural requirements but also support environmental sustainability. As the industry grapples with the dual challenges of resource scarcity and climate change, findings like these present a compelling case for rethinking traditional construction methods.
