Air cooling of concrete by means of embedded cooling pipes—Part II: Application in design
Abstract 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 Södertälje, 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]. Some exemplifying calculations are also shown, and the general behaviour of cooled structures is discussed. The principles of designing a cooling system for a general case are proposed. It is concluded that it is possible to design prismatic structures, such as a columns, by the use of existing models and measured heat transfer coefficients.
