Aggregate-Filled—Flowable

Natural sand is a major component of most flowable fill mixes. Ferrous spent foundry sand can be used as substitute for natural sand (fine aggregate) in flowable fill.48 49 Spent sands from nonferrous foundries and foundry baghouse dust can contain high concentrations of heavy metals that may preclude their use in flowable fill applications. Some of the engineering properties of spent foundry sand that are of particular interest when foundry sand is used in flowable fill applications include particle shape, gradation, strength characteristics, soundness, deleterious substances, and corrosivity. [Pg.188]

Other potential applications include its use as an aggregate in flowable fill, hot mix asphalt concrete, and surface treatments To be used as an aggregate ... [Pg.130]

Construction procedures for flowable fill materials are no different than those for conventional earth backfill materials. The same methods and equipment used to mix, transport, and place flowable fill made with conventional aggregates may be used for flowable fill incorporating spent foundry... [Pg.188]

Bottom ash has been used as an aggregate material in flowable fill mixes Ponded ash also has the potential for being reclaimed and used in flowable fill Since most flowable fill mixes involve the development of comparatively low compressive strength, no advance processing of bottom ash or ponded ash is needed... [Pg.119]

Applications that could potentially make use of SSA in highway construction include the use of ash as part of a flowable fill for backfilling trenches, or as a substitute aggregate material or mineral filler additive in hot mix asphalt... [Pg.148]
