“…The increased moisture content in AAC [23–26] evidently reduces compressive and tensile strengths, and deteriorates insulating parameters. The effect of changed compressive strength of AAC was presented as a function of changes in moisture content expressed as the ratio of absorbed mass of water and mass of dry material:

\begin{equation}w = \frac{{{m_w} - {m_s}}}{{{m_s}}} \cdot 100\% ,\end{equation}

where: m w —mass of wet specimen, m s —mass of specimen dried until constant weight.…”

Sclerometric method, commonly used in reinforced concrete structures, have also found application in masonry structures, mainly in the diagnosis of brick masonry walls or testing mortar in joints. This article presents a proposal for determining the compressive strength of autoclaved aerated concrete masonry elements with the use of the Schmidt OS‐120 PT pendulum hammer. The test was carried out on masonry elements with a nominal density class of 400 and 600. Additional tests were also carried out on samples with different levels of humidity, in order to consider the influence of humidity on the change in rebound number and changes in compressive strength.

“…While defining concrete class, both cube and cylindrical strength experimentally obtained for standard elements is provided. Expanding and solidifying process may affect strength of autoclaved aerated concrete (AAC) [2,3]. If both processes are not synchronized, then pores can flatten and strength of AAC concrete is reduced [2,4].…”

This paper present results from testing shape and dimensions of specimens on compressive strength of autoclaved aerated concrete (AAC) concrete with nominal density classes 400, 500, 600, and 700. The tests were conducted on standard cube specimens 100 mm × 100 mm × 100 mm, cylindrical and rectangular specimens made of AAC blocks. DANTEC optical measurement system was used to analyze how specimen shape affected the mechanism of specimen destruction. Obtained results were analyzed and Neville's algorithm was adapted.
