Describes the properties, performance and test methods of factory made, non-load bearing hollow concrete shuttering blocks made from normal weight or lightweight aggregates or a combination of both.

This European Standard specifies the properties, performance and test methods of factory made, non-load bearing hollow concrete shuttering blocks made from normal weight or lightweight aggregates or a combination of both. Shuttering blocks may include vertical or horizontal interlocking features and factory installed supplementary insulation. Shuttering blocks are intended to be used to form walls and partitions when filled with concrete or mortar. Concrete shuttering blocks rely on a concrete or mortar infill for their structural performance and are not intended to be used unfilled. This standard does not cover masonry units covered in EN 771-3.
