Aluminium Sulfate (Alum)
Aluminium Sulfate or Alum is a major accelerator in the construction industry, used in admixture, drymix, shotcrete and glass-fibre reinforced concrete (GFRC). It is also used in construction as a waterproofing agent. and is a major component of alkali-free shotcrete accelerators.
It has major applications in the water treatment industry, where its large molecular size and weight, combined with low cost, make it an excellent flocculant for the treatment of both drinking water and industrial waste water. Aluminium sulfate is also used in the paper and oil manufacturing processes.
