Thanks Michael. I agree that capturing it at the source seems
better than trying to deal with it after it spreads into the room.
You have a central dust collection system, which I wish we had,
but don't. I am doubtful that we can get permission to exhaust to
the outside, so we have been looking at filtering systems. The
problem there is that it looks like we might be going through a
lot of expensive filters.

We just have students use a vacuum hose or dust collection
hose coming off the main system over the mixer while we pour.
Humidifiers and/or spray bottles can mitigate small batch
problems but sucking up the dust as it is produced seems to
work best. Pulling the bag off the cement instead of pouring
it produces less dust too.
We are planning to do quite a bit of work with concrete and
are concerned about the dust. Our lab is about 1400 square
feet, but in the past, the dust has spilled out into a lot of
the rest of the building which has made quite a few people
unhappy. Most of the dust will be created by a portable mixer
that will move to different locations in the lab. I was
wondering if others had come up with solutions to similar dust
problems, whether concrete, plaster, or like materials?
