Update of concrete guidance

Since CIRIA published Early-age thermal crack control in concrete (C660) in 2007, the subject of cracking of concrete structures due to thermal effects (as well as shrinkage) has continued to challenge researchers and designers. There has been a flow of comments and queries from readers and there has been continued research and discussion in the technical press. The author of C660 (Dr Phil Bamforth) has himself cooperated on further research funded by the Institution of Civil Engineer's Research and Development Enabling Fund as well as dealing with problems and assisting with new-build designs.

During 2011, CIRIA held an industry workshop to discuss the key issues which are under debate and a project has now started to incorporate all that has been learnt into an update of C660. Those who attended the workshop will form the basis of a Steering Group but CIRIA members with an interest in this topic and who would like to be involved should email Alan Gilbertson at CIRIA. There will be a meeting to discuss the proposed amendments on the afternoon of 7 August 2012. It is anticipated that the updated guidance will be published early in 2013.
