This study explores the influence of water–cement ratio and fiber content in engineered cementitious composite (ECC) on mechanical characteristics foamed lightweight soil (FLS) through experimental analysis. Two types materials—ECC ordinary Portland cement (OPC)—were utilized to create FLS specimens under identical parameters examine their performance. Results indicate that ECC-FLS exhibits superior toughness, plasticity, ductility compared OPC-FLS, validating potential ECC as a high-performance material for FLS. To assess ratio, were constructed with varying ratios at 0.2, 0.25, 0.3, while maintaining other constant. The results increases, flexural strength, compressive elastic modulus gradually increase, exhibiting better Moreover, this investigates effect basalt properties While keeping constant, volume fibers varied 0.1%, 0.3%, 0.5%, respectively. demonstrate within range 0 improved increasing content. effectively enhanced strength In conclusion, adoption appropriate can significantly optimize performance FLS, endowing it broader application prospects engineering practices. ECC-FLS, characterized by excellent crack resistance, demonstrates versatile applications. It is particularly suitable soft foundations or regions prone frequent geological activities, where enhances seismic resilience subgrade structures. also serves an ideal construction solution underground utility tunnels, well repair reconstruction pavement bridge decks. Notably, enables resource utilization industrial solid wastes such fly ash slag, thereby contributing carbon emission reduction realization circular economy. These attributes collectively position HDFLS sustainable significant promoting environmentally friendly infrastructure development.
