type 10 (general use) and type 30 (high early) on the same mix

type 10 (general use) and type 30 (high early) on the same mix

Hi everyone,

Just wondering what happens if we mix both types of cement on the same mix? do they interact negatively between them? or will it become like a mid strength HE?

Thanks all.


RE: type 10 (general use) and type 30 (high early) on the same mix

I have not seen anything on the effects of such a practice, but here is my prediction. The cements have different heats of hydration and will cure at different rates. As such, any drying shrinkage that you would have from a single mix would be increased due to additional differential shrinkage. Aside from the cement, the components of the mix will also vary in quantity and/or type, so there are other interactions going on. My advice: don't do it (or if you do it, let us know what happens)

RE: type 10 (general use) and type 30 (high early) on the same mix

Ooooo, I really don't like that. Agree with motor that differential shrinkage would likely occur. That said, I don't think it couldn't work just that I would look at better ways to do this. For example, type 10 (type I in the US) with additives to get the properties you need.

I have no idea if there is any chemical interaction... as noted above, likely a bad idea...
