New Standards for Lime in Stabilisation

The European standard for “Building Lime” BS EN 459-1 : 2010 has been revised and is now available to purchase from BSI. The revised standard covers the use of lime in many building applications, but in the new revision the scope has been extended to cover Civil Engineering and Soil Stabilisation.

EN459-1 allows the user and customer to specify the chemical and physical characteristics of the quicklime or hydrated lime for any given project, which in turn verifies the consistent quality of the product used.

Binder quality and consistency forms an integral part of the overall performance guarantee between Stabilisation Contractors and their customer. When used together with confirmation of compliance to Britpave “Soil Stabilisation – Guidelines for Best Practice” (BP/47), this gives the customer confidence of a successful project outcome.

Stabilisation contractors and their customers can check for compliance by asking their supplier for proof of CE registration.

The standard covers quicklime, hydrated lime, hydraulic and dolomitic lime used in building applications, such as:

  • preparation of binder for mortar (for example for masonry, rendering and plastering);
  • production of other construction products (for example calcium silicate bricks, autoclaved aerated concrete blocks, lime concrete, etc.);
  • civil engineering applications (for example soil treatment, asphalt mixtures, etc.).

The interests of the UK were represented by Steve Foster, on behalf of BSI, the British Lime Association and the Britpave Soil Stabilisation Task Group.
