scope:

This European Standard specifies the properties of lightweight aggregates and lightweight filler aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these aggregates for use in concrete, mortar and grout in buildings, roads and civil engineering works. This European Standard covers lightweight aggregates of mineral origin having particle densities not exceeding 2000 kg/m3 (2,00 Mg/m3) or loose bulk densities not exceeding 1200 kg/m3 (1,20 Mg/m3) including: a) natural aggregates; b) aggregates manufactured from natural materials and/or from by-products of industrial processes; c) by-products of industrial processes; d) recycled aggregates. It provides for the evaluation of conformity of the products to this European Standard. The requirements specified in this standard may not be relevant to all types of lightweight aggregates. For particular applications the requirements and tolerances may be adapted for the end use.
