expansive concrete

expansive concrete

(OP)
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?  

RE: expansive concrete

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.

RE: expansive concrete

(OP)
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.  

RE: expansive concrete

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

RE: expansive concrete

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