...Jennifer E. Nicks; Ismaail I. Ghaaowd; Michael T. Adams Foamed glass aggregates (FGAs) are an emerging material in the US for use as a lightweight structural backfill. Manufactured from recycled glass powder mixed with a foaming agent, FGAs are considered a sustainable solution with advantageous...

... ash as an alternative backfill material in geocell walls. This study also provides an approach for the use of waste plastic water bottles as geocells. The geocell diameter and height used in the model testing is 70 mm. Two types of structural geometry were considered in the study: gravity wall type...

...J. C. Damm; M. R. Lewis; K. H. Stokoe, II; D. P. Moore The construction of a new nuclear power plant requires an excavation over 27.4 m (90 ft) deep. The excavation is backfilled with compacted sandy soils. The power plant is embedded about 12.2 m (40 ft) below grade; thus bearing on about 15.2 m...
