splatgirl-

This will be more than a 2 bag project. I was just saying 2 bags because that is what fits in a mixer and how I would be adding the color. You can see my build if you want.

- I plan on cast in place for around the oven and a mold for the prep area next to it. I would get them both ready to pour at the same time (one after the other to use the mixer effectively).

Nic- (or anyone else)

Is counter-flow a dry powder or a liquid. I looked it up at Fishstone, is that the stuff?

Powder. At least the jar I've had around for a few years.

So I got my supplies, and I was going to try and pour a couple of test pieces for the color. I don't have any reference of where to start from.

-How much Iron Oxide would you typicaly use per bag (roughly)?

I was going to do 2 one bag tests to get an idea what the coloring would do. I will use a wheelbarrow to see how easy it is (if it works that way).

As a rule, most iron oxides will use 2-2-1/2 # per bag of portland per yard. It can vary widely though, so you have to test it.

I was planning on using sakcrete 5000 bags (80lb).
Following Nic's
2 80lb sacs of Sakcrete 5000+
8 oz counterflow
12 to 14 quarts warm water
dry color to taste, always use iron oxide based colors not carbon based.

And the Cheng style of method.

Mike,

Sorry - I haven't kept up on this thread, but have you heard of the Quikcrete Countertop Mix?

42x80# sack=1 cuyd, so your range will be 10/42=.23# per sack to 12.5/42=29# per sack of color.
