Testing the Influence of the Material Bonding System on the Bond Strength of Large-Format Tiles Installed on Concrete Substrate under Mechanical Loading

Abstract

The paper describes an experiment focusing on the way the material system influences the bond strength of large-format tiles installed on concrete substrate during mechanical loading under conditions that correspond to real-life application. This involves a controllable mechanical load applied over an area of a test model while observing its condition using non-destructive methods (ultrasonic pulse velocity test, acoustic emission method, strain measurement, and acoustic tracing). The model consisted of a concrete slab onto which were mounted four different systems with large-format tiles with the dimensions of 3 m × 1 m. The combinations differed in the thickness of the tile, the adhesive, and whether or not a fabric membrane was included in the adhesive bed. The experiment showed that the loading caused no damage to the ceramic tile. All the detected failures took place in the adhesive layer or in the concrete slab.

Analysis of tiles produced from a schist material and their ultraviolet, near-infrared, mid-infrared, longwave-infrared and far-infrared spectra

“…Due to the lack of previous studies on the production of tiles from schists originating from Rızapasa or similar locations, these compressive strength values were compared with those recommended in tile production standards. Topolář et al (2020) placed a mechanical load on a reinforced concrete tile in increments of 5 kN m –2 , starting from 10 kN m –2 (0.10 kg cm –2 ). When the mechanical load on the concrete tile reached 35 kN m –2 , the stress on the structure increased with further increase of the load.…”

A Proposal to Improve the Effectiveness of the Deflection Control Method Provided by Eurocodes for Concrete, Timber, and Composite Slabs

“…Controlling the maximum deflection is particularly hard in the case of RC structures, where the occurrence of concrete cracking and presence of concrete creep affects both the short-and long-time deflection of horizontal members. Since the limit values defined by Eurocode 2 [4] do not depend on the type of superstructures or finishes (including their application method [5]), they can provide non-reliable results, especially when stiff and brittle elements, such as ceramic or stone tiles (a quite common solution in Mediterranean countries), are used as floor finishing.…”

Special Issue: “Non-Destructive Testing of Structures”

“…The second group of papers has been devoted to the condition assessment of concrete and cement-based materials and structures [9][10][11][12][13][14][15][16][17]. Szel ąg [9] presented a paper in which he reviewed the achievements in the field of the diagnostics of the cracking in cement composites.…”

“…The next two articles concerned bonding between a concrete substrate and cladding. Topolář et al [16] experimentally examined the influence of the bonding system between a concrete substrate and large-format tiles. The bond strength was observed during mechanical loading under conditions that corresponded to real-life applications.…”

“…Non-destructive diagnostics were performed using the following techniques: ultrasonic pulse velocity test, acoustic emission method, strain measurement, and acoustic tracing. The experiment showed that the loading caused no damage to the ceramic tile and all the detected failures took place in the adhesive layer or in the concrete slab [16]. Wojtczak et al [17] applied the guided wave propagation technique for the condition assessment of concrete beams strengthened with steel plates.…”
