Energy efficiency improvement of aerated concrete block wall fences

Abstract

Abstract The development of effective protecting structures is currently one of the most popular areas in the construction industry. In order to ensure energy efficiency and environmental safety in the construction of civil buildings, masonry made of aerated concrete blocks with high thermal protection properties is used as protecting structures. As glue and cement-sand solutions in masonry have low thermal conductivity and are temperature bridges, the issue of filling through seams of aerated concrete masonry is very acute. The authors have developed a double row of concrete masonry, having a minimum number of cross-cutting horizontal seams, which not only improves thermal insulation properties, but also reduces material consumption and, consequently, the complexity of the arrangement of protecting structures of civil buildings. The influence of through horizontal seams made of cement-sand grout and block binding on the resistance to heat transfer of masonry made of aerated concrete blocks is considered.
