CAS - Composite Anode Systems GmbH, Vienna (Austria)
CAS Composite Anode Systems Gmbh (CAS) is an innovative small enterprise founded in July 1999 and operative since 2001. The main business activities of CAS are R&D, implementation of novel & innovative concepts, technologies and materials for the repair, rehabilitation and maintenance of concrete structures exposed to environmental stresses. Engineering and consulting support is an essential part of the activities of CAS. CAS readily cooperates with research facilities, innovative companies as well as customers such as public building administrations. CAS has an in depth experience in the chemistry of hydraulic binding materials. The R & D is based largely on the evaluation of QXRD, in-situ XRD, ESEM, standard characterization techniques of renders and coating materials. CAS has an extended experience in electrochemical characterization techniques such as solid state pH measurements and solid state resistance measurements in mortars.

Role in the Project
CAS will co-ordinate the work of the cement producers in WP1 to ensure that optimum cements are produced. It will also co-ordinate the hydration studies executed by Partners 1, 2, 4 and 5 to ensure that maximum account is taken of the interpretations developed within the ROCEM project, WP2. CAS will further perform the studies on carbonation in mortars related to water transport with solid state pH and resistance probes.
