CAS - Composite Anode Systems GmbH, Vienna (Austria)

CAS Composite Anode Systems Gmbh (CAS) is an innovative small enterprise founded by Dr Schwarz 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.

Wolfgang Schwarz, director of CAS, received his doctoral degree 1979 at the Department of Technical Chemistry at the Swiss Federal Institute of Technology. He received his first training in the coordination in R&D, both industrial and industrial related, at the IBM research facilities at San Jose, CA. during his engagement as visiting scientist from 1980 to 1982. Scientific R&D at the University level followed from 1982 to 1986 in the field of solid state chemistry & electrochemistry, as well as with consulting projects for industry. He managed environmental related projects developing and implementing novel technologies for SGP (now VA Tech) in Vienna, Austria in cooperation with several universities and several subcontracting companies. He managed a task force for HOLCIM Ltd, Switzerland for the development of a novel product line of highly durable and rapid hardening cements. He played a leading role in co-ordinating the hydration studies in the ROCEM project.

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.
