Determination of resistance of sealed joint to compression stress

Original language description

Mankind has been dealing with the issue of sealing since the very beginning of construction. Sealed joints are exposed to several external influences, whether physical or mechanical. These effects also include compressive stresses on the sealed joint. If we know that the structure in which the sealed joint will be placed will be exposed to compressive stress, we should choose a suitable sealant regarding this fact. A sealant suitable for sealing joints subjected to compressive stress should have sufficient flexibility after it has hardened. If the sealed joint is not flexible enough, its pressure load can significantly damage the sealed joint, and thus damage the entire structure. This article deals specifically with the sealing of problematic material. Aquapanel cement board is selected as a problematic material for the purposes of the presented research. The tested sealants are selected based on the manufacturer's recommendations on the suitability of these sealants for sealing cementitious materials. Furthermore, primers are used, which are again selected according to the manufacturer's recommendations. Test samples are made from selected materials, which are further conditioned according to a predetermined schedule. Then these samples are tested according to the European standard. Specifically, the resistance of a sealed joint subjected to compressive stress is tested. After exposing the test specimens to this stress, the sealed joints and their possible failure or deterioration are evaluated. The test results are recorded and further evaluated. Based on the evaluation of these results, it is possible to recommend all tested sealants for sealing cementitious materials, except acrylic sealant. The sealed joint made of acrylic sealant shows significant cracks in this test. These cracks are caused by the insufficient flexibility of this type of sealant and thanks to them the sealed joint is considerably degraded.
