The backfill material for the underground pipe wall of Yellow River embankment was developed to avoid the high settlement and environmental damage caused by high filling and excavation. The interrelation between microstructure and compressive strength of the self-compacting foam backfill material with different water-binder ratios and density grades was investigated. The results indicated that the average pores size of the foam backfill material increased with increasing the water-binder ratio. Moreover, the compressive st
