The unit’s research in concrete durability has been on-going for more than two decades and has led to a better understanding of the deterioration mechanisms of concrete.
Test methods for the durability of concrete developed by CoMSIRU researchers have now been refined to a point where they are now within the SABS system for acceptance as national standards. Also, the revision of SANS 10100-2 will incorporate research outputs in terms of concrete durability clauses.
CoMSIRU’s research has instilled a comprehensive approach to condition assessment and strengthening of concrete structures, which may be noted by the input into national codes and standards, where research findings are being reflected. The unit’s publications, specifically the series of monographs that are produced are regularly supplemented by new material. As far as scientific papers are concerned, the output of CoMSIRU is substantial, and the vast majority appear in internationally respected journals and conferences. New approaches from this research continue to be applied in major national construction projects.
