What is BS EN 1367-1 - Freezing and thawing resistance of aggregates about?
BS EN 1367 is a European standard for testing the thermal and weathering properties of aggregates. The main aim of the BS EN 1367 series is to ensure increased durability and service life of aggregates used for construction purposes.
BS EN 1367-1 is the first part of the BS EN 1367 series that specifies a test method that provides information on how an aggregate behaves when it is subjected to the cyclic action of freezing and thawing.
The results provide a means for assessing an aggregate's resistance to this form of weathering.
The test is applicable to aggregates having a particle size between 4 mm and 63 mm.
Who is BS EN 1367-1 - Freezing and thawing resistance of aggregates for?
BS EN 1367-1 on freezing and thawing resistance of aggregates is useful for:
- Builders
- Contractors
- Civil engineers
- Manufacturers of concrete and concrete products
- Mineral materials and products manufacturers
- Manufacturers of bituminous products and aggregates
- Quality control and testing authorities
Why should you use BS EN 1367-1 - Freezing and thawing resistance of aggregates?
The ability of materials used in industrial constructions, such as concrete and coatings, to resist cyclic freezing and melting is referred to as freeze-thaw resistance.
In a cold climate, aggregate freeze-thaw resistance is critical, because it can cause aggregate deterioration. The cumulative effect of multiple freeze-thaw cycles on the concrete structure, as well as the disturbance of paints, coatings, and aggregates, can eventually cause expansion, cracking, scaling, and crumbling.
In this regard, BS EN 1367-1 provides the apparatus requirements, test sampling, and preparation of test specimens to evaluate the freezing and thawing resistance of aggregates.
The test technique described in BS EN 1367-1 is designed to explore freeze-thaw resistance and clarify the impacts of various aggregate parameters like exposure to freezing under water.
As a result, if you are a manufacturer of aggregates, adhering to BS EN 1367-1 can demonstrate the performance and credibility of your product, ensuring that it is fit for purpose.
