Abstract- The Temple of Hatshepsut was constructed during the reign of Queen Hatshepsut to worship Idol Amun Rai,
in the modern state and specifically in the eighteenth family and is characterized by a unique architectural style and is
considered one of the best temples constructed in that period 3500 years ago in Deir el-Bahari.
This temple was built from Thebes limestone extracted from the ancient quarry in Gebel Qurna. Considering the age at
which this temple was built and its exposure to severe environmental condition such as temperature change and relative
humidity, this building gradually deteriorate with time and cracking and spalling are seen on the surface of the building.
This effect of deterioration resulted to structural disintegration and ultimately detrimental to the integrity of the
masonry. The study therefore aimed at using suspension of Nano fluids synthase from Thebes limestone in coating the
surface of the building to reduce the effect of deterioration, the destruction of its distinctive architectural facades, and the
obliteration of its colors.
This study further investigates the structural, petrological and mechanical characteristics of the Nano Thebes limestone
using the Transmission Electron Microscope, X-Ray Diffraction, and Fourier-transform infrared spectroscope. In
addition to this, a number of test were performed, the compressive strength test, thermo analytic test (TGA/ DTA) and
the microstructural test on the experimental Thebes limestone and the one coated by Nano Synthases. Results of the study
ultimately show that treatment of Thebes’s limestone with Nano fluid synthases enhances the aesthetics, strength, and
ability to withstand environmental conditions over thousands of years. And, preserves the architectural details of the
facades and the colors used. Which is the ultimate goal of the study for the purpose of conservation and sustainability of
heritage building.
Keywords: Deterioration, Nano Fluid Synthases, Transmission Electron Microscope, The architectural facades of the
temple, X-Ray Diffraction, and Fourier-transform infrared spectroscopy.
I. INTRODUCTION
Temple of Hatshepsut acquired distinctive architectural value due to the architectural style and unique
architectural facades that the colors covered and given it the beautiful value made it one of the most important of
Deir el-Bahari Temples. This uniqueness of architectural value had become in serious danger due to the sharp
deterioration and laceration arising from vulnerability to environmental factors such as moisture which would be
called for urgent intervention through untraditional processing methods to maintain the unique value. Temple of
Hatshepsut considered one of the most important of Mortuary Temple in Deir el-Bahari which includes main three
temples are Mentuhotep II, Hatshepsut, and Thutmose III. The Hatshepsut temple is an unusual design of the ancient
Egyptian temples which typically consisted of the gigantic structure (huge gate), Hypostyle Hall, the smaller
structure followed by Hypostyle hall then third structure, followed by Hypostyle hall ends to chapel. While the
Temple of Hatshepsut consists of the arcade instead of the structure, the terraces one another is above each other
instead of Hypostyle Hall, those terraces are connected by cliffs. The outstanding design of the Temple of

Hatshepsut which consists of followed three-story with open terraces. The horizontal projection has shown Figure
(1) is one of the reasons exposure its facades to environmental factors led to damage of facades and the impact of the
inscriptions that carry significant artistic and historical values. Also, the traditional methods in restoration are
worthless under direct exposure to environmental factors which requires more of the search for more effective
material to face increased exposure to the facades with three- story (Figure 2) which increases the rate of interaction
with weathering which results in damage to Inscriptions and colors. Figure.(3)

Figure 3: The Inscriptions and colors of the Hatshepsut Temple were affected as a result of exposure to environmental factors
Ancient Egyptians constructed houses, palaces, temples and tombs mainly of environmental stones (Falana
et al., 2020) and limestone and sandstone was the most commonly used materials in the construction of sacred
buildings in Egypt because of its resistant to harsh weather. During the period of Queen Hatshepsut, Hatshepsut
temple was built of local materials from Thebes limestone extracted from ancient quarry in Gebel Qurna (Aubry et al.,
2009), (Pawlicki, 2017) (King, 2017). The study of Graue et al., (2007) revealed that severe deterioration results into
the structural disintegration of rock masses, which is as a result of a clearly pronounced cataclastic overprint and has
become a major structural problem since the tomb’s origin. An example can be seen in figure 4 which shows the
deface of the sculpture of Queen Hatshepsut, which is as a result of hazard of rockslides, extreme salt contamination
in certain areas, and the disintegration of the surface of the stone by carbonation process (Graue et al., 2007). Figure
5 also shows the status of the temple surface and the extent of the deterioration resulting from the fall of rock slides
(the picture shows from the entrance of the temple at beginning of the restoration processes in the temple since 1954).

Hatshepsut temple suffered intense erosion as the micro-environmental conditions are critical to conserve
Hatshepsut temple mortars wall, paintings and carved hieroglyphs. Mohamed et al., (2019) found that the expansive
properties (swelling) of Esna Shale with the presence of ground water is one of the major factor causing the
separation between the Esna shale formations under laid by Thebes limestone, causing possible collapse of the cliffs,
particularly where deep fissures have developed, these causes the rockslides under the effect of natural hazards.
Bashed & Sediek (1997), further stressed that the Thebes limestone are of low to medium strength rocks with low
modulus ratios according to Deere's (1968) classification. Thus, the pronounced structural disintegration of Thebes
limestone (carbonation processes) has to be dealt with, complete structure needs to be stabilized and the surface need
to be treated to preserve the ancient buildings. Recent studies interested on the role of material’s characteristics in
deterioration and conservation. Using unsymmetrical polymeric materials to coat Thebes limestone causes some
restoration problems. However, this study look into coating the sample gotten from heritage buildings with Nano fluid
synthases to increase the strength, durability and possibly extend its service life. The petrological tests are carried out
by using the scanning electron microscope (SEM) method and the X-ray diffraction (XRD) technique. Figure 6 below
illustrate the feature of stone after coated by polymeric materials ((Derluyn et al., (2014), (Abdellah et al., 2017)),
Therefore, investigating the properties of the materials used in coating of Thebes limestone is substantially to
integrate conservation approach.

II. EXPERIMENTAL TECHNIQUES
The purpose of this study is to investigate the structural, petrological and mechanical characteristics
of the Nano Thebes limestone using the Transmission Electron Microscope, X-Ray Diffraction, and Fourier-
transform infrared spectroscope. Experimental Thebes limestone coated by Nano Thebes limestone was also
examined using the uniaxial compression strength machine, thermo analytic technique (Differential Thermal
Analysis (DTA)/Thermal Gravimetric Analysis (TGA)) and Scanning Electron Microscope (SEM).
2.1 Ball milling
Nano fluids are suspension of Nano calcium hydroxide derived from Thebes limestone which
synthase by Ball milling process, to obtain this fresh samples of Thebes limestone selected from ancient
quarry at Gabel el Qurna, samples were crushed into powder by hammer and the powder of the Thebes
limestone was milled by Ball milling process (Sopicka et al., 2010), (De Gisi et al., 2017) to a Nano size at
Nano materials laboratory south valley university.
2.2 Transmission Electron Microscope (TEM)
Transmission Electron Microscope (TEM) is used to describe morphology, size, shape, and
arrangement of particles on a scale of atomic diameter, crystallographic information, and compositional
information (Pavel Zinin, 2006). Figure 7 below shows the TEM photographic examination of Nano size
from Nano materials which synthesis from environmental Thebes Limestone (impurity). TEM test was done
at central Mansoura University lab.

2.5 Compression Mechanical Test
24 Samples from old Thebes limestone quarry at Gabel Al Quran near the Valley of the Kings were cut as
cubic shape. Figure (10) shows comparison stress /strain curves for sample of limestone without coating and coated
Thebes limestone, cubic samples of limestone of (30 mm ×30 mm ×30 mm) is tested in compression using the
computerized universal testing machine (model WDW-100) at 1mm/min crosshead speed. The compression test is
carried out according to ASTM D2938-95 adopted by Abdellah & Mohamed, (2014). The samples of the coated
limestone were tested until cracks appeared then the machine was stopped. The result from the compression tests
illustrated the strength of the Thebes limestone was significantly increased when coated with Nano powder.

2.6 Thermo Analytic Test (TGA/ DTA) thermal gravimetric analysis (TGA)
Thermal stability of the treated samples was studied by the thermal gravimetric analysis (TGA) / Differential
thermal analysis (DTA) at thermal analysis unit at the central Laboratory of Assuit University. Figure 11 shows the
thermal stability of sample of limestone coated with Nano calcium hydroxide, this can be seen in the DTA curve. It
also shows there is no defusing in the heat peak before 400o C which means thermal stability of a coated sample
signifies a good property via decay factors and environmental changes.

III. DISCUSSION AND CONCLUSION
Results from the study illustrated that Nano fluid synthases can be used in the treatment of ancient buildings
to reduce the effect of deterioration when expose to environmental conditions. Properties of Thebes limestone and
coated Thebes limestone was investigated and analyzed. The study shows that using the same material to coat,
prevent the ancient building of the changes of microstructure of materials due to environmental impacts. More so, the
coated material and the building material are from the same material obtain from the same ancient quarry. Synthetic
Nano materials of Thebes limestone was used to treat the pore space and initial cracks of the building stones, TEM
shows the Nano size and shape of synthetic Nano environmental Thebes Limestone, Fourier-transform infrared (FT-
IR) spectroscopy illustrate the impurity of the coated materials due to the depositional ecology, XRD patterns shows
the presence of clay minerals in the coated materials which is also present in the building materials which means the
environmental impaction will be of little effect.
The study also indicated that mechanical properties of coated limestone are better than uncoated samples,
microstructural analysis of coated and uncoated samples is clear by SEM analysis, the particles of synthetic Thebes
limestone was used in the filling of the pore space and micro cracks of limestone. Thermal stability of sampled
limestone coated with Nano Calcium Hydroxide, which cleared in DTA curve means that the coated sample signifies
a good property via decay factors and environmental changes. Therefore, the study concludes that using same
materials in treatment of ancient buildings means actual sustainable concept. In general, experience has shown that
using nanotechnology to process old buildings reduce its vulnerability to environmental factors and maintains
Inscriptions, colors, and architectural styles of facades.
