Popis:	This paper relates the second part of the investigation of air-cooling in concrete; the first part is presented in “Air cooling of concrete by means of embedded cooling pipes—Part I: Laboratory tests and heat transfer coefficients” [1]. Embedded cooling pipes are used to reduce the risk of thermal cracking in early age concrete. Traditionally, water has been used as a cooling medium, but air cooling has been shown to be advantageous for many applications. The experimentally-determined heat transfer coefficients of cooling pipes [1], have been used and verified in comparisons ofin situ measurements at the Igelsta Bridge in Sodertalje, Sweden. The close agreement between measured and calculated temperatures of air-cooled sections seems to justify the use of the averaged heat transfer coefficients determined in [1].
