Binders for floor screeds based on calcium sulphate - Part 2: Test methods

This document describes the test methods for binders for floor screeds based on calcium sulphate specified in EN 13454-1. In addition, some of the described test methods apply for factory made mixtures for floor screeds based on calcium sulphate specified in EN 13813.
This document describes reference test methods. If methods and conditions other than these are used, it is important to show that they give results equivalent to those given by the reference methods. In the event of a dispute, only the reference test method is used.
This document describes test methods for binders and made mixtures where the principal active component is calcium sulphate.

Overview

EN 13454-2:2019 - published by CEN - specifies reference test methods for binders for floor screeds whose principal active component is calcium sulphate. It supports the product requirements set out in EN 13454-1 and, for some tests, applies to factory-made screed mixtures covered by EN 13813. The document defines laboratory conditions, sampling rules and a suite of standardized tests used for quality control, conformity assessment and technical specification of calcium sulphate binders.

Key Topics

• Scope and status
  • Reference test methods for calcium sulphate binders; in disputes only the reference method is valid.
  • Introduces differentiation for stiff versus flowing mixtures (2019 update) and working time tests.
• General test conditions
  • Use distilled or deionized water; laboratory water temperature should match room temperature.
  • Apparatus must be non-reactive to calcium sulphate (glass, stainless steel, plastics, etc.) and scrupulously clean to avoid influencing results.
  • Sampling for binders per EN 196-7 and EN 459-2.
• Main test methods covered
  • Content of calcium sulphate - digestion with hydrochloric acid, removal of insolubles, and gravimetric determination of sulphate as barium sulphate (BaSO4).
  • pH determination - dispersion of pulverized sample in water and pH measurement.
  • Setting time - procedures to determine initial (and for flowing mixtures specific) setting behavior.
  • Mechanical resistance - strength measurement methods for cured specimens.
  • Shrinkage and swelling - dimensional stability testing.
  • Working time - practical time available for placing and finishing mixes.
• Test report requirements
  • Results, sampling details, methods and any deviations from reference conditions must be recorded.

Applications

EN 13454-2:2019 is intended for:

• Manufacturers of calcium sulphate binders and factory-made screed mixes - to perform factory QC and support product declarations.
• Independent testing laboratories - to deliver accredited, repeatable test results for compliance and certification.
• Specifiers, architects and contractors - to verify product performance data (setting time, strength, dimensional stability) when selecting screed binders for residential or commercial floors.
• Regulatory and conformity bodies - for assessing conformity with EN 13454-1 and resolving technical disputes using the reference methods.

Practical uses include incoming raw material checks, R&D comparisons, pre-delivery inspection and verification of declared working times and mechanical properties.
