Grout Mix for Pump Primer
Grout Mix for Pump Primer
(OP)
I have a new slab on metal deck on top of an existing building.
My contractor is requesting to use a grout mix as a pump primer and to leave it in the slab.
The grout mix is of the same compressive strength as my slab on metal deck mix.
To me, this seems REALLY far fetched. Has anyone had a similar request?

I doubt it will be the same compressive strength as the concrete.

I've seen it attempted to be mixed in with the concrete once, with abysmal results.
Also, usually concrete pumps up here carry their own dry slurry mixed with water off of the concrete truck or their own truck for slicking (is that even a word?) the line and it's discharged somewhere on site (NOT in the forms).

Yeah the discharge of the slick pack is a slimy mess, never placed in the forms.
