REACH consortium "flue dust from cement clinker production"

REACH consortium "flue dust from cement clinker production"

A consortium has been put in place and managed by Cimeurope to prepare a joint REACH registration dossier (including chemical safety assessment, chemical safety report, exposure scenarios and guidance on safe use) for the following substance (preliminary description):

Flue dust from production of cement clinker (covering the EINECS entry "Flue dust, portland cement" with EC number 270-659-9)

  • A complex combination of finely divided inorganic particles separated from the exit gases formed during the manufacture of cement clinker which is produced by thermal processing of raw materials (naturally occurring minerals and/or alternative raw materials) and fuels (fossil and/or alternative)
  • The composition is based on the EINECS entry for "Flue dust, Portland cement", all known constituents in concentrations above 10% (w/w) are given:
    • Total clinker phases: 0-100%
      • Alite (3CaO.SiO2 or Ca3SiO5), belite (2CaO.SiO2 or Ca2SiO4), aluminate (3CaO.Al2O3 or Ca3Al2O6), ferrite (4CaO.Al2O3.Fe2O3 or Ca4Al2Fe2O10)
      • Other clinker phases: CaO, CaAl2O4, Ca2Al2SiO7, CaAl4O7, Ca4Al6SO16, CaAl12O19, Ca12Al14Cl2O32, Ca12Al14F2O32, Ca12Al14O33, Ca6Al4Fe2O15, Ca2Fe2O5 and other intermediate calcium aluminates and calcium silicates
    • Raw materials (eg CaCO3, SiO2, MgCO3, Ca(OH)2)): 1-100%
    • Alkaline chlorides (eg KCl, NaCl, CaCl2): 0-55%
    • Alkaline sulfates (eg CaSO4, K2SO4): 0-55%
    • Other minerals (MgO, (Ca,Na)2(Al,Mg)[(Si,Al)2O7], Ca3Mg(SiO4)2, Ca5(SiO4)2CO3): 0-40%

The Consortium is open to all legal entities which are manufacturers or importers of the above mentioned substance or to only representatives of outside EU manufacturers of that substance.
