Concrete by Use of Stone Dust and Fly-ash
We use stone dust instead of sand
Stone dust is a waste material obtained from
crusher plants. It has potential to be used as par-
tial replacement of natural river sand in concrete.
... Results showed that by replacing 60% of fine
aggregate with stone dust concrete of maximum
compressive strength can be made as compared
to all other replacement levels.
What is the difference between sand and dust?
Sand particles are larger than dust particles, are not launched far and fall out of the air faster.
The particles in a dust storm are smaller in size than particles in a sandstorm and can be
launched higher and farther.
