通告描述：

This Draft Rwanda Standard specifies the characteristics and performance requirements of aggregate concrete masonry units made from dense and lightweight aggregates or a combination of both for which the main intended uses are common, facing or exposed masonry in load bearing or non-load bearing building and civil engineering applications. The units are suitable for all forms of walling, including single leaf, external leaf to chimneys, cavity wall, partitions, retaining, and basement. They can provide fire protection, thermal insulation, sound insulation and sound absorption.
This Standard is applicable to aggregate concrete masonry units of an overall non-rectangular parallelepiped shape, specially shaped and accessory units.
This Standard does not specify standard sizes for aggregate concrete masonry units, nor standard work dimensions and angles of specially shaped aggregate concrete masonry units.
It does not apply to:
a) storey height panels, chimney flue linings or units intended for use as a damp-proof course;
b) units with an incorporated thermal insulation material bonded to the faces of the unit susceptible to be exposed to fire.
