Determining propertires of polyures coating as a material potentially strengthening structural elements
MetadataShow full item record
The paper discusses the results of experimental research on polyurea. In authors’ opinion, this material could be used to improve load-carrying capacity and integrity of structural elements made of various materials. The paper presents the results of research on basic mechanical properties of polyurea, its impact on integrity of cellular concrete specimens and full-scale concrete rings. The additional polyurea layer on outer surfaces of test specimens improves mainly their integrity following their complete failure. It must be noted, however, that when the additional layer is present, it does not improve all strength properties of test specimens such as resistance to compression of cellular concrete specimens. It was revealed that this property may be negatively influenced by the level of constrainment.
