Soil parameters for dry mix concrete as backfill to retaining wall

Soil parameters for dry mix concrete as backfill to retaining wall

Soil parameters for dry mix concrete as backfill to retaining wall

(OP)
I am looking at a failing wall with a backfill with a phi value of 30 degrees and no cohesion.
One solution is to excavate the backfill and replace it with material with a higher phi value and/ or cohesion. One material being considered is dry mix concrete or possibly no fines concrete.
Has anyone any parameters for these materials or any other suggestions?

RE: Soil parameters for dry mix concrete as backfill to retaining wall

Take a look at flowable flyash backfill, lightweight (expanded) aggregate, or tiebacks.
