Sandstone blocks were used in the construction of Luxor temple. However, they, especialy cement materials, were at a great risk because of being affected by various deterioration factors. Groundwater started to rise in and around the temple, causing serious deterioration aspects of the blocks. Therefore, the current study was conducted to focus on the role of pores and cement regarding the deterioration process of sandstone blocks in the temlpe. In order to conduct systematic investigation, it adopted SEM-EDX, PLM and XRD. Also, physical and mechanical properties were examined to evaluate the components of the sandstone, under the present environmental conditions. It also interpreted the investigations of onsite evaluation tests (non-and less-destructive). It also focused on other methods, e.g. humidity and salt analysis. The study ended develops some recommendations that fit sandstone address in Luxor Temple.

Granite columns were studied using [PLM], [XRD], [XRF] and [SEM]. The results of the study showed that the ground water mixed with sewage water caused granite damage, which also depends on the ability of ground water to rise through the pores and cracks of the granite as a result of previous damage factors and rise the ground water level is -0.5 m. The radioactivity in the air, water, soil, rocks and sunlight at the archaeological site has an important role in the damage, in addition to the radioactivity resulting from the uses in life, which increases the effect of the radioactivity affecting the mineral grains of the granite at the study site, which leads to acceleration of deterioration processes. Additionally, the recommended materials that can be used to consolidate and treat granite were studied.
