What is BS EN 1367-7 – Testing thermal and weathering properties of LWA about?
BS EN 1367 is a European standard on 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 1367-7 is the seventh part of the BS EN 1367 series that specifies the reference test method used for type testing, and in case of dispute, for determining the resistance to freezing and thawing of lightweight aggregates (LWA) in accordance with EN 13055.
For other purposes, in particular, for factory production control, other methods may be used provided that an appropriate working relationship with the reference method has been established. The test is applicable to LWA with particle size not less than 4 mm and up to a maximum size of 32 mm.
Who is BS EN 1367-7 - Testing thermal and weathering properties of LWA for?
BS EN 1367-7 on lightweight aggregates is useful for:
- Builders
- Contractors
- Civil engineers
- Construction industry
- Manufacturers of bituminous products and aggregates
- Quality control and testing authorities
Why should you use BS EN 1367-7 - Testing thermal and weathering properties of LWA?
LWA is a kind of coarse aggregate that is used in the production of lightweight concrete products like concrete blocks, structural concrete, and pavement ensuring the strength, workability, and durability of concrete and asphalt materials, and even used to enhance the final appearance of structures and pavements.
In this regard, the test technique described in BS EN 1367-7 is designed to explore freeze-thaw resistance and clarify the impacts of various lightweight aggregate parameters (density, water content, crushing strength, and pore structure) and freezing rates on freeze-thaw resistance.
Overall, BS EN 1367-7 walks you through the LWA criteria to prevent expansion and cracking, scaling, and crumbling of the concrete utilized in your construction.
As a result, if you are a manufacturer of lightweight aggregates, adhering to BS EN 1367-7 can assist demonstrate the performance and credibility of your product, ensuring that it is fit for purpose.
