Aggregate specification for concrete amended

BSI Group, a leading global business services organization, has announced the amendment of BS EN 12620, which specifies the properties of aggregates and filler aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these aggregates for use in concrete.

It covers aggregates having an oven-dried particle density greater than 200 mg/m3 (2,000 kg/m3) for all concrete, including concrete in conformity with BS EN 206-1, concrete used in roads and other pavement, and concrete for use in precast products. BS EN 12620 also covers recycled aggregate with densities between 150 mg/m3 (1,500 kg/m3) and 200 mg/m3 (2,000 kg/m3) with appropriate caveats and recycled fine aggregate (4 mm) with appropriate caveats.

BS EN 12620 specifies that a quality control system is in place for use in factory production control, and it provides for the evaluation of product conformity.
