Adhesion and cohesion of the sealed joint after exposure to water

Original language description

This article deals with the sealing of problematic cement-based building material and its adhesion and cohesion after exposure to water. Aqupanel cement board is chosen as a problematic material for the needs of this research. Furthermore, sealants are selected according to several criteria. These criteria include the manufacturer's recommendations on the suitability for use of cementitious substrates, affordability, and commercial availability for the average consumer. The selected sealants, the so-called primers, are then used for selected sealants. Test specimens are made of selected materials, which consist of two cement base plates, a primer, and an applied sealant. These test specimens with correctly matured sealant are further conditioned and tested according to the European standards ČSN EN ISO 8339 and ČSN EN ISO 10591. The results of these two tests are carefully recorded in the result tables and then evaluated and compared. These results show that for a tensile test without the use of water, it is necessary to apply a greater tensile force for the failure of the test specimen than for a tensile test after exposure to water. Furthermore, based on these results, we can say that polyurethane sealant is more resistant to tensile stress than acrylic sealant, for which the value of maximum elongation at failure of the test specimen is even several times higher.
