TS EN 14016-1

TS EN 14016-1 addresses the definitions and required properties of caustic magnesia and magnesium chloride used as binders in magnesite screeds. It provides a technical framework for identifying the binder materials intended for magnesite-based screed materials and magnesite screeds, helping align material selection with a shared set of requirements.

In general technical terms, magnesite screed is a floor screed based on a magnesium-binder system. Caustic magnesia refers to a reactive magnesium-oxide-based material obtained by calcination of magnesium carbonate, while magnesium chloride is the component that participates in the binding reaction and helps form the hardened matrix. The balance between these ingredients is important for workability, setting behaviour, and end-use performance.

How the binder system is understood in practice

Linked to the terminology of EN 13318, this subject is about the constituent materials behind the screed as much as the screed itself. The standard focuses on the required properties of the binders used in magnesite screed materials, rather than on a full installation method or a complete product system. In practical use, these binders influence the screed’s cohesion, surface performance, and suitability for the intended flooring application.

Why this document matters

• It establishes a common technical reference for binders used in magnesite screeds.
• It frames the properties by which caustic magnesia and magnesium chloride are identified and assessed.
• It connects the binder materials to the EN 13318 terminology for magnesite screed materials and magnesite screeds.
• It represents the current TS EN 14016-1 edition in the TSE catalogue.
