What is BS EN 13454-2 - Binders for floor screeds about?
BS EN 13454 is a series of European standards on binders used in concrete for building construction.
BS EN 13454-2 is the second part of the BS EN 13454 series of documents that describes the test methods for binders for floor screeds based on calcium sulphate specified in EN 13454-1.
BS EN 13454-2 also 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.
Who is BS EN 13454-2 - Binders for floor screeds for?
BS EN 13454-2 on test methods for binders for floor screeds is useful for:
- Manufacturers of concrete
- Civil engineers
- Builders
Why should you use BS EN 13454-2 - Binders for floor screeds?
A screed binder is a cementitious binder based on hydraulic binders and special additives to replace cement in conventional aggregate-based floor screeds providing quick-drying indoor and outdoor cementitious screeds with high strength and low shrinkage.
BS EN 13454-2 describes test methods for binders and made mixtures of calcium sulphate for floor screeds and gives the equivalent test results of parameters such as pH-value, setting time, mechanical resistance, shrinkage and swelling and working time.
BS EN 13454-2 instructs you regarding the igniting temperature and duration of ignitions of the specimen, such procedures help the user attain quality and control.
Overall, BS EN 13454-2 could help you manufacture high-quality binders for floor screeds for interior use in buildings to give a smooth and level floor with both high strength and rapid installation properties.
What’s changed since the last update?
BS EN 13454-2:2019 supersedes BS EN 13454-2:2003 +A1:2007. BS EN 13454-2:2019 includes some technical changes with respect to BS EN 13454-2:2003 +A1:2007. These includes:
- The title is adapted and the normative references are updated
- The terms 'flow diameter' and 'spread' are interchanged
- A differentiation between binders for stiff and flowing mixtures is introduced
- The setting time for binders for flowing mixtures is introduced
- The working time for binders and factory-made mixtures is introduced.
