Question

Can we use quarry dust to build walls instead of sand? ?

Answer 1

Many and I mean many years ago I did a concrete pump job at NOAA in Boulder Co.The aggregate was a red rock and the fines were crushed too.That was perhaps one of the toughest days of my life.

Using a dust (fines) alone doesn't sound like a viable option.There needs to be a bonding agent to hold things together.This would be cement powder and aggregate for a designed strength.

Answer 2

By quarry dust I assume you are talking the dust that is produced from the crushing of granite. I'm not quite sure what kind of wall you are talking about but if it's something that is requiring regular washed sand then probably not.  Quarry dust is super fine and similar to mason sand which is fine like sugar.
