Compound Design for Continuously Cast Concrete to Underlie an Extensive Ice Layer in the 13th National Winter Games Venues

摘要

This paper details the design process and testing procedure used to create frost-resistant concrete for this engineering project, which involved considering properties such as tendency to shrinkage and durability. Through the examination of performance indices, it is shown that the designed concrete mix met the requirements of the design and of construction through continuous casting, specifically C40F250 concrete with a low shrinkage rate, good performance under freeze-thaw conditions, and no cracking under the pressure of an extensive layer of ice.
