What is coarse sandstone?

Coarse sandstone, was introduced in the Roman and Byzantine times, "Istanbul is the stone known as" the only piece that survived for a long time, such as 2000-2500 years. The most important feature right out of the soil is suitable and easy processing of all transactions; air by absorbing carbon dioxide the air after contact with the hardness, strength and power to acquire.

That is why, the Byzantines, the Hagia Sophia and the construction of the Süleymaniye Mosque complex Yukarıkapı Walls of Istanbul since the Ottoman period with the construction of all buildings that make up the aesthetics of the foundation stone always has been in and out.

Climatic feature of coarse sandstone, which is also a stone. Sweltering in the summer by absorbing heat and freezing cold in the winter helps you get a sigh of relief. In addition, coarse sandstone, a study conducted at the University of Moscow in 1986, underwent nuclear waves was also found. Coarse sandstone, Istanbul Technical University (ITU), the chemical analysis of white cement, lime, gypsum, detergent powder, the powder can be used as raw material in the making.

Characteristics of coarse sandstone,

1.Organik sedimentary stone. Limestone, silica and fossil (such as oysters and mussels) is composed of sediments.

2.Açık beige, light yellow, shades of gray, fine grained and sandy appearance, fossiliferous, porous and crystalline, compact stone.

For extraction of quarried around 3.Bakırköy "Bakırköy Move" or "Silivri Stone," "lümaşelli limestone" and "maktralı limestone known as".

Before 4.Ocaktan soft. Therefore, the processing is very easy. Then, taking the carbon dioxide gas in the air hardens. This continues for a long time erection. Over the years in relation to the concrete strength increases even more. (In this area of ??research: research on this subject: http://www.ym.com.tr/formdata/PDF/kufeki1.pdf).

5.Küfeki stone tensile, compressive, shear strength decreases and the elapsed time, while the pores in the formation of water, gas emissions, increasing the resistance to external disturbances.

Does not change its properties in the presence of 6.Su.

7.Bizans and Ottoman periods were used as basic building blocks of many important architectural work. (Walls of Istanbul, Silivri Bridge, Aqueduct, Silivri Mosque, Topkapi Palace, Suleymaniye mosque, etc.). Always in and out of all the structures that make up the aesthetics of Istanbul has been the foundation stone.

8.Mimar Sinan, and easy processing of coarse sandstone, carried out research on the special, due to the characteristics of this stone in his works, such as aesthetics and strength. Coarse sandstone, and the subtleties of usage locations used by the works of Mimar Sinan, standing firmly in the works ever seen.

9.Sadece exterior wall material, not the internal spaces, floor coverings, arches, columns, jambs, cumbalarda, harpuştalarda, fireplaces, garden arrangement, reliefs, portal, altar and pulpit were also used.

In the restorations of ancient monuments 10.Günümüz architecture and new buildings, villas and lively, garden walls, walkways, camellias and other places used.

Tras 11.Çimento sector (pozzolan) were used as specifications. (Research on this subject: http://www.maden.org.tr/resimler/ekler/682cc30db9c025e_ek.pdf).
