expansive concrete

[rmccabe]

I am trying to find non-shrink cement or an expansive admixture. Type K from Blue Circle seems not to be available. I heard about calcium aluminosulfate and gypsum, but I don't want to have to do a lot of blending and testing. Anything off the shelf?

You could contact your local Cement Institute or Concrete Society to get names of manufacturers of pre-packaged products.
Some manufacturer/product names that come to my mind are
Fosroc, Sika, Conbex, Denka and Vandex.

Thanks for the response. These are good names, especially Denka, but I don't see any evidence that any of them are selling expansive cement, or grouts, or admixtures in North America.

I am in South Africa. Afraid I don't have any other leads for you.

We sometimes use bentonite in grout mix for boring closures. Not sure if this would work as admixture in concrete though.
