The structure of the rig from inside to outside is formed by substrate, bonding layer, insulation layer, reinforced base coat, and finishing coat (see Figure 3).
To monitor the distribution of the temperature at different positions and structural layers along the horizontal and vertical directions of the test wall surface, the strain gauges and temperature sensors in preparing ETICS GHB should be installed at the same positions as the concrete base, the insulating layer (outer surface), and the finishing coat.
1) As shown in Figure 7, the temperature changing trend at different measuring points on the surfaces of the finishing coat and the insulating layer are similar and have a shape of a rectangular wave.
Furthermore, the fluctuations at the measuring point T-III-7 of the finishing coat are more significant than those at the other points in the middle part, indicating that there is an unbalance in the local temperature in the test chamber.
For the purpose of comparison, the measured temperatures near each measuring point, the strain-time-temperature relationship curves of the finishing coat, insulating layer, and bonding layer at different positions were depicted in Figures 9, 10, and 11.
1) As shown in Figure 9, for each period at the temperature rising and maintaining phases, the strain of the finishing coat changes synchronously with the temperature in the external layer.
The finishing coat shrinks at early stage and expands after a number of cycles.
2) Figures 9 and 10 show the results of the strains on the surfaces of the finishing coat and insulating layer.
The horizontal strains in the finishing coat and the total strains in the insulating and bonding layers increase continuously with a relative slowly rate until the end of the test.
In these two instants, the cracks and swells on the finishing coat appeared as lines and circles.
1) On the surface of the finishing coat (see Figure 15), most of the cracks are in the horizontal direction, the second to most of the cracks are vertical ones, and very few of the oblique cracks appeared.
2) As shown in Table 4, the number, the length, and width of the cracks on the surface of the finishing coat gradually increase with the increase in the number of cycles.
