Determination of the Dry Density of Autoclaved Aerated Concrete
Also Known As:
The standard DIN EN 678 establishes a method for determining the dry density of autoclaved aerated concrete (AAC). It specifically applies to prismatic specimens of AAC that have been conditioned in a controlled environment. The document outlines the detailed procedure to be followed in order to obtain accurate and reliable results.
The standard emphasizes the importance of ensuring that the specimens used for testing are representative of the AAC product being evaluated. The conditioning process involves storage in a controlled environment to achieve a moisture equilibrium. The specimens are then weighed and their dimensions measured before being placed in a drying oven. After a specified period of time, the specimens are removed from the oven, cooled, and reweighed. The difference in weight, along with the dimensions, is used to calculate the dry density of the AAC.
The method described in DIN EN 678 provides a systematic approach for determining the dry density of autoclaved aerated concrete, allowing for consistent and comparable results. Adhering to this standard ensures that the testing process is conducted in a standardized manner, facilitating accurate data collection and enabling meaningful comparisons between different samples of AAC.
