Use of Controlled Density Fill in Silo Floors
Use of Controlled Density Fill in Silo Floors
(OP)
Does anyone have experience in the use of controlled density fill (CDF) where the depth of the fill will be 11'-0"+-? We are designing the Tunnel for the reclaimer and floor slab for a 55' dia.x112' high grain by-product silo. They want the floor slab on the CDF rather than constructing a floor. Load will be 3500 psf.
My questions are:
-What strength of CDF do we need?
-Is there any special concerns about the ring around the perimeter supporting the end of the reclaimer (5k load)?
-Should this be poured in lifts each lift will have a chance to set up (water has no where to go)? CDF will be poured over a matt foundation?
