On the load-carrying ability of anchor clamping under the influence of axial loading in AAC

Research results of the load-carrying ability of plastic facade anchors in AAC concrete depending on the actual values of average density, compression strength, and moisture are described. It has been established that, in terms of the impact degree, the relationship distributes as follows: AAC compression strength, average density, moisture.

There is an increasing tendency in construction to use energy-efficient autoclaved aerated concrete (blocks, slabs, panels) [1-3] as a walling material, which brings much concern about high quality and efficient fastening of various detachable equipment and furniture to AAC. No system research has been conducted on this subject, though there appear many odd bits of information, that require systemization and conceptualization [4-8], including those of an advertising nature [9].

Attachment of various items, structures, equipment, furniture etc. to structural components has been a long-standing...
