The effective cross-section thickness and its effect on shrinkage

What is it about?

In concrete structures such as bridges or tanks, water insulation is applied several months afterwards regarding the actual construction of the structure itself. The concrete structures dry during certain part of their lifespan throughout the entire area of their structure. After the insulation is applied, the drying process is affected and does not occur as it would under normal conditions. This change in drying conditions can eventually lead to changes in the structural behaviour of the structure as a whole, e.g. bridges or tanks. Current computing programmes for time related analysis of the structure do not allow us to take into consideration the above mentioned conditions in the process of drying thus leading to static analysis inaccuracies. The aim of this article is to experimentally demonstrate the shrinking process as a result of the difference in the drying processes of the concrete structural elements and their basic comparison with the calculations according to different standards.
