DYI Rock - What Cement????
 

All I can fine for Portland cement is "General Portland 10" Can this be used to make LR. I can't find any other portland on Vancouver Island, Nanaimo area. Please Help

Thanks

That cement is fine. Canada uses typ 10, 20 and 30. in the US it is type 1, 2 and 3. So type 10 in Canada is type1 in the US.

Cheers,

type 10

Mike, did you find the curing time reasonable with type 10? that's what I've used but I haven't started curing it in the water yet.

I Found that the curing time ws really fast in the rock ,due to having made it very pourous. And the coraline grows fast.

sorry for the 2x posts

Porosity makes a difference, very interesting idea, I'll give that some thought then.

Also there is low pH cement and my choice white cement....
got @ Sledges in Victoria

I went with the white as well, but I believe it's low Alk not low pH.
