Description
Hongjun Zhang and colleagues engineer a flowable stabilized soil for narrow trench backfilling in a 2026 materials study. Tight urban utility trenches resist traditional compaction, so a pumpable fill made from local loess, fly ash, and cement activated by sodium silicate was optimized through ratio tests. Microscopy and flow simulations traced hardening workings and pour behavior in confined trenches.
An even fly ash to cement split anchored the recipe, with set water, activator, and curing agent shares balancing flow against strength. The best mix spread widely yet hardened to solid strength within two weeks, meeting pumping and strength demands. Microscopy showed binding products filling pores and gluing particles. Field pours using long single runs with end slowdowns compacted well. The authors offer guidance for utility tunnel construction in the region.
