Table 1 The features and chemical composition of plastering samples
Sample number | Sample features | Lab number of layered sample | Test items |
|---|---|---|---|
HLG-1 | The original structure of HLG-1 was destructed by rainwater, and there were many slender fibers could be observed in HLG-1. | Fiber analysis | |
HLG-2 | Two layers in the section of HLG-2, the surface layer is dark reddish-brown and the base layer is light reddish-brown. Both layers contain fibers. | Surface layer: HLG-2S | Grain size analysis Chemical composition analysis X-ray diffraction analysis Infrared spectroscopic analysis Simultaneous thermal analysis |
Base layer: HLG-2B | Grain size analysis Chemical composition analysis X-ray diffraction analysis Simultaneous thermal analysis | ||
HLG-3 | Three layers in the section of HLG-3, the outermost layer is modern lime layer. The original surface layer is dark reddish-brown and the base layer is light reddish-brown. Both of two original layers contain fibers and white particles. | Surface layer: HLG-3S | Grain size analysis Chemical composition analysis X-ray diffraction analysis Infrared spectroscopic analysis Simultaneous thermal analysis |
Base layer: HLG-3B | Grain size analysis Chemical composition analysis X-ray diffraction analysis Simultaneous thermal analysis | ||
HLG-4 | Same to HLG-3. | Surface layer: HLG-4S | Grain size analysis Chemical composition analysis X-ray diffraction analysis Infrared spectroscopic analysis |
Base layer: HLG-4B | Grain size analysis Chemical composition analysis X-ray diffraction analysis | ||
HLG-5 | Same to HLG-2. | Surface layer: HLG-5S | Grain size analysis Chemical composition analysis X-ray diffraction analysis Infrared spectroscopic analysis |
Base layer: HLG-5B | Grain size analysis Chemical composition analysis X-ray diffraction analysis |
