The basis of the association's work is to promote the scientific and practical development and dissemination of non-metallic reinforcements in concrete construction. This includes networking, exchange of experience and collaboration between members and external institutions from the fields of business and science, politics and administration as well as the public. By direct letters, position papers, statements or by inviting members to own information and networking events as well as meetings, contact with politicians is sought directly in order to create optimal conditions for climate-neutral construction with carbon concrete in the Federal Republic of Germany.
