Self- healing of cracks in concrete long-term exposed to different types of water : results after 1 year exposure
SUMMARY The aim of the project was to find out if cracks in concrete exposed to water can heal so that chloride ingress in the crack is effectively obstructed. If this is the case it might be possible to accept wider cracks in concrete than is allowed today. 18 concrete specimens with induced cracks, 0.2 and 0.4 mm wide, were exposed to sea water, brackish water and tap water for 1 year. For most
