New concrete cancer threat
Series: New Civil Engineer ; 18 November 2004, 10(1)Publication details: 2004Subject(s): Summary: Bridges, dams, tunnels and other major structures are threatened by the return of concrete cancer according to a leading specialist. The phenomenon, properly known as alkali aggregate reactivity, causes massive cracking in affected structures. Many structures were repaired after the problem occurred in the late 1970s and 1980s. Research carried out then resulted in changes to materials specifications to limit alkali content. It is thought that the increase in use of recycled aggregates like glass has been a trigger for the problem reoccurring now.| Item type | Current library | Call number | Copy number | Status | Date due | Barcode | |
