Based on this, marble reserves are estimated at 2.16 billion, granite at about 1.5 billion tons, travertine at about 450 million tons, and marble at 44 million tons. The number of decorative Natural Stones extracted in the country last year was 10.6 million tons. The amount of extraction of decorative stones in the country last year was 10.6 million tons.

Building stones should be light. The buildings should not be technically heavier than a certain limit. Therefore, according to the materials and bearing of each structure, the appropriate stone should be used. Some building stones are very heavy and strong and some are light. Of course, this lightness is a reason for less strength than heavier stones. 

Marble is often associated with prestige, luxury, and grandeur. In West Asia, marble has cultural and symbolic significance, representing power, wealth, and architectural excellence. Its use in religious buildings, palaces, and important public structures reflects the region's cultural heritage and artistic achievements.

Its weight is high and its use puts a dead load on the building. Installation of this stone is time consuming due to the use of mortar for adhesion. This stone is not thermal and acoustic insulation, thus leading to energy loss in the building. Granite adhesion to mortar is not ideal. For this reason, its use as a paving stone has recently been banned because it is likely to fall.

Marble can be resistant to most rock against the environmental conditions such as humidity, heat and cold. The rock also has good resistance against rain and acidic rain. Stone structure is in a way that is rarely infected, and keep its beauty for a long time.Other features marble are as follows:

Moreover, travertine is considered a sustainable choice in architecture and design. It is a natural stone that is widely available, and its extraction and production processes have become more environmentally friendly over the years. Additionally, travertine has excellent thermal properties, helping to regulate indoor temperatures and reduce energy consumption.

It can be said that it is a stone between marble and lime found in abundance near hot springs, especially limestone caves. The large cavities in the texture of this rock, as mentioned, are caused by gases trapped in hot water and make the surface of the rock, not polished and slippery, and a good choice for the floor of places that experience high humidity.

Travertine stones are usually available in ivory white or completely white and caramel. More common colors are naturally more economical as well, while stones with rarer colors are often much more expensive.

When the sandstone is transformed into quartzite, the quartz grains that were already there are crystallized again along with the cementitious material that was previously present in the sandstone, and the new quartz crystals are fused together. Most or all of the old sandstone texture and sedimentary structure will be completely removed by metamorphism and replaced by a new structure.

The formation of rocks, which are sandstones, is such that they are permeable to water and their porosity is such that they can hold large amounts of water, which makes them precious watersheds. Fine-grained watersheds such as sandstones are more prone to filtering contaminants from the surface than rocks such as limestone and other rocks formed by seismic activity. 

GDP per capita in this country has also grown by 3%. Gross domestic product from agriculture in Egypt has grown by 12 percent, while the GDP of construction in this country is estimated at 1 percent. It is clear that the GDP policies of the mines in this country have grown by 10%, and the Egyptian economy, which is dependent on the GDP of the public transport sector, is also growing by 4%.
