Investigation of sorption properties in crushed autoclaved aerated concrete waste

open access: yesJournal of Environmental Engineering and Landscape Management, 2012
Due to hardening in autoclaves and mechanical processing of autoclaved aerated concrete (AAC) massive, the process of production of AAC unavoidably generates waste. Up to now, there were no ways for utilisation of this type of waste.

Impact Sound Insulation of Thermally Insulated Balconies

open access: yesINTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2022
AbstractWith the increasing urban densification, balconies are gaining in popularity as they improve the living quality in homes. From a technical point of view, the thermal insulation between balconies and the building’s façade is state of the art. In Germany, the most popular balcony construction is a reinforced concrete balcony, separated from the ...
