This part of PD 6682 gives guidance on the use 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. BS EN 12620 covers aggregates having an oven dried particle density greater than 2 000 kg/m³ for all concrete, including concrete conforming to BS EN 206‑1 and concrete used in roads and other pavements and for use in precast concrete products.
