1、BSI Standards PublicationLight weight fill and thermal insulation products for civil engineering applications (CEA) Expanded clay lightweight aggregate products (LWA)BS EN 15732:2012BS EN 15732:2012 BRITISH STANDARDNational forewordThis British Standard is the UK implementation of EN 15732:2012.The

2、UK committee voted against the approval of EN 15732 due to duplication of content covered in BS EN 13055-2. Both standards cover the requirements for all types of lightweight aggregate, including expanded clay and for all loose-fill construction applications including civil engineering applications.

3、The users attention is also drawn to several inconsistencies found by UK experts: Clause 4.3.2, the reference to EN 14063-1 for the method to determine the thermal conductivity of expanded clay lightweight aggregate is incorrect, however, users are advised to refer to EN 12664. There is also limited

4、 guidance given on how to obtain design thermal values from such measurement results. Clause 4.3.3, the direction to use EN ISO 10456 to determine specific heat capacity implies that the standard contains a test or calculation method whereas it only gives tabulated values of specific heat. Clause 4.

5、3.8, contains test requirements for loading, which are at variance with those in Annex C to which it refers. Clause 4.3.10, contains test requirements for loading, which are at variance with those in Annex B to which it refers.Annex E, the table in Annex E gives k10,dry values which are inappropriat

6、e for the application. Used below ground, the expanded clay is unlikely to be dry so the values given are too low to be used as design values and therefore, cannot be considered safe.The UK participation in its preparation was entrusted to Technical Committee B/540, Energy performance of materials c

The standard covers the use of expanded clay LWA as lightweight fill and insulation materials in embankments for roads, railways and other trafficked areas and as lightweight backfill for structures. This standard does not specify the required level of a given property to

31、be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this do
