Resistance of a sealed joint subjected to tensile stress at different temperatures

Abstract

In this paper, research on the topic of Resistance of a sealed joint subjected to tensile stress at different temperatures is presented. Tensile stress is one of the physical effects acting on conventional structures. This research specifically deals with the sealing of problematic material. Aquapanel cement board is chosen as the problematic material. This board has a large amount of fine dust particles on its surface, which prevent the sealant from adhering properly to the base material. Next, two sealants and the appropriate primers are selected. The sealants used were selected based on the manufacturer's recommendations on suitability for use in sealing cementitious materials. From these three components, the Aquapanel cement board, the sealant and the primer, test specimens are made, which are tested according to the valid European standard. The results of this test are carefully recorded and further analysed. Based on the results of this test, it is possible to recommend both tested sealants for sealing cement materials that are exposed to tensile stress at different temperatures.
