Zuschlagsstoffe
Zuschlagsstoffe is a term used in German-speaking technical contexts to describe substances that are added to a base material in order to influence its properties or processing, without being the main constituent of the final product. They serve to adjust performance, workability, durability or cost, and can be inert fillers or active compounds. The term is used across industries and can overlap with other categories such as Zusatzstoffe, Füllstoffe or Verstärkstoffe, depending on the application.
Typical categories and examples include:
- Füllstoffe (fillers): inert materials added to adjust volume, density, or texture, such as mineral aggregates in
- Additive compounds (Zusatzstoffe): substances that modify processing or performance, including plasticizers, stabilizers, lubricants, or coupling agents.
- Verstärkende Mittel: fibers or particulates used to improve strength and toughness in composites.
- Flussmittel and chemische Zusätze: in ceramics or metallurgy, chemicals that influence melting, binding or microstructure.
- Pigmente und Oberflächenschutzmitteln: pigments for color and surface protection.
Applications span concrete technology (Zuschlagsstoffe like Sand, Kies, Zuschläge in Beton), plastics and rubber (additives and
Quality and regulation focus on specification-compliance and compatibility with the base material. Properties such as particle
