COMPARATION OF LABORATORY AND IN-SITU TEST RESULTS OF MECHANICAL AND DURABILITY CONCRETE PROPERTIES FOR STADIUM STRUCTURE

Abstract

One of the key issues for concrete structures exposed to weathering, besides all other loads, is durability of concrete. The most exposed concrete structures are stadiums. Destruction mechanisms for concrete structures defined by EN 1504 are: mechanical
actions, chemical action, physical action, corrosion of reinforcement and fire. In this paper, the tests conducted on the case study stadium "Rodjeni" in the city of Mostar, are presented. The stadium consists of three grandstands, built in different periods, but with concrete of the same quality and class. North grandstand is 17 years old, west grandstand is 14 years old, and east grandstand was built in 2022. A series of in-situ tests to evaluate mechanical and durability properties were implemented, primarily on north and west grandstand. In addition to in-situ tests, laboratory tests were conducted on the same concrete, to evaluate mechanical and durability properties in laboratory conditions. These results are compared and presented in this paper.
