Increasing the thermal uniformity of walls made of cellular concrete blocks

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 adhesive and cement-sand solutions in masonry have low thermal conductivity and are temperature bridges, the issue of filling through seams of cellular concrete masonry is very acute. The authors have developed a double row of concrete masonry, as well as single-row masonry on polyurethane adhesive, which allow reducing the deformability of the enclosing structure on polyurethane adhesive due to the device of fixators in the form of glass composite rods in the vertical seams of the masonry and directly into the blocks. The paper also presents a study of the reduced resistance to heat transfer of the enclosing structure, taking into account heat-conducting inclusions, on the basis of which a conclusion is made about ensuring the energy efficiency of the developed wall fences due to the increased thermal uniformity of the masonry.
