摘要
The present invention relates to a backfilling method which secures weight lightening and re-excavation ability by pouring and mixing a foaming agent into mortar including Portland cement and fly ash cement as a bonding material, and produces a self-compacting and rapid hardening light-weighted foam mortar compound improving working time efficiency on site by additionally adding a strength development accelerant, while depositing the mortar compound in an excavation part.
