Been an exchange on other posts regarding using a Cemenitious Grout
under steel base plates to concrete raft.

Thought I'd break this question out to a separate thread ...
To mix the grout it states :
"a high shear paddle or vane grout mixer should be used, colloidal
impeller mixers are not suitable. Air entrainment should be avoided"

Anybody know what the difference is in these types ...

The only mixer I have is described as a "Paddle Mixer" see;

Is this a 'high shear' type ???

If my type is not suitable .. then suggestions on mixing this, other
than a stick in a bucket ?

I know very little about mixing grout but it seems to me that the high
sheer type would have vertical paddles whilst the colloidal type will
have the paddles as part of a helix so that when the paddles revolve the
vertical paddles "merely" mix the "stuff" whilst the colloidal mixer
lifts the mixture up to let air in
