The advantages of using a lightweight fill include accelerating construction, reducing structural resistance requirements for lateral and vertical loads, reducing the magnitude of and time for consolidation of soft soils and settlement of embankments and structures, and eliminating or reducing stability issues.
BS EN 15732 is a European Standard that discusses lightweight fill and thermal insulation products for civil engineering applications (CEA).
BS EN 15732 describes the product characteristics and includes procedures for testing, marking, and labelling for loose-fill expanded clay LWA products for CEA.
Note: BS EN 15732 does not specify the required level of a given property to 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.
BS EN 15732 on expanded clay LWA for CEA is useful for:
The abundant numbers of small, air-filled cavities in clay lightweight aggregate (LWA) give its lightweight, thermal as well as sound isolation characterises.
BS EN 15732 is the harmonised part satisfying the mandate, the CPD, and is the basis for the CE marking, which covers the products which are placed on the market.
BS EN 15732 specifies the requirements for loose-fill expanded clay LWA products for CEA excluding the use as thermal insulation in and under buildings which are covered by EN 14063-1.
BS EN 15732 covers the use of expanded clay LWA as lightweight fill and insulation material in embankments for roads, railways, and other trafficked areas and as lightweight back-fill for structures.
BS EN 15732 guides you with the requirements, test methods, sampling, conditioning, designation code, evaluation of conformity, marking, and labelling for expanded clay LWA. As a manufacturer of aggregates, testing in compliance with BS EN 15732 helps to demonstrate the performance and quality of your products.
BS EN 15732 is useful to reduce dead loads and improve the fire ratings of concrete in numerous construction projects.
