does sand cement slurry penetrate gravel base ?

does sand cement slurry penetrate gravel base ?

(OP)
I am placing a bottomless vault in a pit on a two foot bed of compacted aggregate, the backfill of vault will be 2 sack sand cement slurry,

any chance the slurry will soak into the gravel and prevent it from draining ? Any journal article or other quotable sources available ?

thanks

Andy

Yes. Journal article not necessary

place geosynthetic or 8 mil poly in the bottom to separate and your problem solved

RE: does sand cement slurry penetrate gravel base ?

What is the gravel like? What is the slump of the slurry?

If it is an open graded gravel only, then it will penetrate upto a couple feet depending on the size, gradation, and shape of the gravel. If it is a sand/gravel mix, then it should only penetrate a few inches.

If your vault is big enough, it should be such that it will still drain even with some slurry penetration around the edges.

This is not a journal or calculation thing. It's just experience and common sense. Slurry is a fluid. The soil at the bottom is a sort of filter. The more viscous the fluid and the tighter the filter, the less it will penetrate. The opposite is true with less viscous and more open respectively.

What is the exact definition of "gravel". - There many factors like gradation and particle shape.
