Abstract
The long-term behaviour and physical and mechanical properties of external walls made of rendered autoclaved aerated concrete (AAC) show a great variety under different exposure conditions related to climate and geography. The performance of the porous system depends greatly on its moisture characteristics and the severity of the agents acting within its microenvironment. In order to gather systematic data on the actual in-service performance of rendered AAC walls, an international research programme was initiated to provide continuous microenvironment monitoring of rendered AAC blocks naturally exposed on a test rack and rendered AAC test panels mounted at the field exposure station. In the experimental study, a comparison is made between the environmental exposure data at local and micro levels, and the performance assessment of different rendering systems based on the data and results of continuous moisture measurements at micro scale is presented.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
