Autoclaved aerated concrete

Technical aluminium flakes, aluminium powders,aluminium paste

Aluminium powders and aluminium pastes are delivered in the light weight concrete industry.

Due to its high degree of thermal insulation, its low weight (stone densities of 300 – 700 kg/m3) and the ability to be processed easily, autoclaved aerated concrete is a highly valued building material.

It is available in forms from wall blocks to large reinforced panels for industrial construction, complete wall components and entire prefabricated houses. Increasingly, ultra-light insulation boards made from aerated concrete with densities of 100-150 kg/m3 are used for building insulation.

The pores in these building materials are generated by the reaction of fine aluminium particles with the alkaline aerated concrete mass. Strength and other structural characteristics are achieved in a hardening process in so called autoclaves.

Aquapor

The Aquapor® series includes dust-free aluminium paste preparations consisting of aluminium powder, water and stabilizing additives.

These pastes in a soluble matrix are characterized by excellent dispersion and, at the same time, a high degree of stability in the paste suspension.

DEG

In contrast to the Aquapor® water pastes, the DEG pastes contain diethylene glycol (DEG) as a pasting substance.

These pastes are recommended for use wherever high storage temperatures and long transportation routes require excellent storage stability.

Aerated concrete aluminium powders

Produced from aluminium grit using wet or dry grinding in a ball mill.

By varying the production process, particle size distribution and, if required, post-treatment of the aluminium particles, performance properties such as reaction start time, reaction speed, the resulting pore structure and casting stability are adapted to meet the requirements for the building material (bulk density, strength, etc.). Effective quality controls and an international technical application service are the foundation of Schlenk`s position as a market and technology leader.
