Positionspapier „Beton ohne Steinkohlenflugasche": Veränderung der Betonbauweise aufgrund abnehmender Verfügbarkeit von Steinkohlenflugasche und anderen Kraftwerksnebenprodukten als Zusatzstoffe für Beton.

Position paper "Concrete without hard coal fly ash" – Change in concrete construction due to decreasing availability of hard coal fly ash and other power plant by‐products as additives for concrete Due to the gradual phase‐out of coal‐fired power generation, significantly lower volumes of hard coal fly ash produced in Germany are already available today. By 2038 at the latest, their share will fall to zero. The German Society for Concrete and Construction Technology (DBV) and the Federal Waterways Engineering and Research Institute (BAW) are pursuing the aim of this position paper to inform all those involved in construction about the resulting supply bottlenecks of hard coal fly ash and to create understanding. In addition, in this paper they show initial approaches to solutions to minimize the negative effects on concrete construction as far as possible. [ABSTRACT FROM AUTHOR]
