Aluminium functional powders 
for the building industry

The air cell structure in the final AAC (Autoclaved Aerated Concrete) is a result of the reactivity of the aluminium component. Particle size distribution, hydrogen evolution test, blain, … are some of the parameters influencing the process. The aluminium contributes to the thermal and acoustic insulation properties of all types of AAC. Over the years, AAC products have become increasingly lighter in accordance with the new building requirements and energy saving objectives. Our newly developed grades cater to this trend.

Aluminium Functional Powders for Plasters, mortar and grouts

Recent tests have shown that also in non-autoclaved applications such as plasters and dry mortars, aluminium powders cause the mixtures to expand, thereby compensating the shrinkage that occurs during settling and reducing crack formation.

Recommended dosage:
0.005%-0.01 % for plaster
0.01% - 0.5% for dry mortar

Overall the use of AVL Aluminium powders for AAC in the building industry is essential for:

  • Smooth process
  • Homogeneous gas formation
  • Increased production 
  • Energy savings
  • ….

Aluminium functional
powders for
the chemical industry

Aluminium powders for chemical reactions such as TiO2 production:

Ilmenite is a titanium iron ore. Under high temperatures ilmenite reacts with aluminium in an exothermal reaction, producing pure Ti and Fe and Al2O3 particles.

FeO·TiO2 + 2Al Al2O3 + Fe + Ti

Excellent dispersion of the aluminium in water is a crucial parameter.
Products also available as pastes in DEG
