FIELD: construction.
SUBSTANCE: invention relates to the field of building materials and building construction elements, namely to the set of concrete bricks, consisting of multislot ordinary brick (OB) with central slots, separated by spacers and opened to the end surfaces of brick, and more than twice more narrow septal brick (SB), which have similar protrusions and recesses on the end faces corresponding to them. In the claimed set of concrete bricks, all inner surfaces of bricks, including the central slots of OB, are designed with riffles or asperities, besides the peaks and troughs of riffles are curvilineal and are displaced relative to each other on adjacent slots, in this case all slots of OB and SB, except the central slots in OB are nonthrough.
EFFECT: improving the sound-insulating characteristics of walls without increase of construction costs, as well as providing comfort and ease of masonry works.
