Shear Strength Tests in a Lightweight Floor System with Cement and Polyurethane Adhesives


The article presents static shear tests of adhesives connecting various types of lightweight floor system (LFS) composites with a heating coil. This method is approved for use, and its advantage is the reproduction of the real working conditions of a light floor. Preliminary tests were carried out to determine the point shear strength of selected adhesives and the target ones, using a strain gauge method of deformation measurements. Three types of adhesives used in the lightweight heated floor system were researched-cement deformable, type C2S1, C2S2, and polyurethane BondT8. In addition to determining the maximum shear stress, deformation and approximate displacement of adhesives in this type of composites, the Kirchoff’s and Young’s modulus were also calculated. The method used did not allow determining Poisson’s ratio. Thanks to the three-sided model of sticking the tiles outside its outline, it was possible to determine what the maximum shear stress occurs on the edges of the floor. This is important, due to the highest LFS stresses occurring in these places, confirmed by the analyses contained in the literature cited in this article.
