Liquefied stabilized soil (LSS) is made with construction waste and used for filling and backfilling long, confined spaces where traditional compaction is difficult. Using LSS helps speed up construction processes while reducing costs, wastage, and environmental impact.
Now, researchers have developed a superior, high-flowability LSS from construction sludge with better mechanical properties and fluidity than conventional LSS, which could make the construction industry more sustainable. Now, researchers from Shibaura Institute of Technology, Japan have developed a superior, high-flowability LSS from construction sludge with better mechanical properties and fluidity than conventional LSS, which could make the construction industry more sustainable.
One such example of circularity in construction is liquified stabilized soil , which comprises construction-generated soil or construction sludge that is mixed with a solidifier and intermediately treated. LSS is already widely used in construction sites, especially for filling long, narrow spaces where compaction by earthworks is challenging. The utility of LSS as a construction material lies in its flowability, which makes it easily pourable, and its strength after solidifying.
This paper was published in Volume 8, Issue 5 of Recycling on 30 August 2023."Advances in LSS could transform the construction industry and urban development. Urbanization is increasing the demand for space-efficient construction solutions, and LSS and HFLSS made from RCS could be the answer.
"These findings position HFLSS from RCS as a promising sustainable material for large-scale civil engineering projects. Future research on improving this material could revolutionize the construction industry. Overall, its implications are vast -- from reduced construction waste and environmental impact, to faster, more efficient urban development, which would benefit economies and promote a sustainable future for generations to come," concludes Prof. Inazumi.
