Filling in a Concrete Core

Filling in a Concrete Core

Filling in a Concrete Core

(OP)
We will be taking some concrete cores from a bridge this winter, and will need to fill in the holes. Do to cold temperatures, a portland product that I know of isn't really viable (IE Non-shrink grout). The cores will be 6" in diameter.  What else is out there?   

RE: Filling in a Concrete Core

Use a sand-filled epoxy.  You'll probably need to keep it warm during curing.  A structural injection epoxy with oven dried sand added should work fine.

Thanks for the responses, I'll look into each one. We're definitely going to have to find something on the 'dry' side because of the neg. batter.
