Building stone properties
Masonry is a form of masonry used in the construction of buildings. Building blocks vary. We find basalt, granite, limestone, sandstone, and many others, and each type is suitable for different uses and is extracted from huge hard rocks from quarries, and these stones must be free of any cracks and be strong so that they can resist various weather factors.

basalt
Basalt is an igneous rock, which is very dense and hard, and has many physical properties. It is dark in color, ranging in color from gray to black, and consists mainly of plagioclase and pyroxene minerals.

In addition, it has a low corrosion rate, as it contains 50% silica, which makes it a good resistance to weathering factors due to its extreme hardness. It is widely used in roads and in the construction of dams and sidewalks, as its compressive strength ranges from 200 MPa to 350 MPa.

granites
Granite is abundant in nature, and its compressive strength ranges from 100 MPa to 250 MPa. It is also considered a volcanic rock, and it is characterized by the lack of pores, which means its low absorption capacity, which makes it a weak resistor. It is widely used in indoor fireplaces, and as a result of its low porosity, it is also used in floors, walls and columns due to its resistance to water penetration, and its colors range from light gray to pink.

sand stone
Sandstone is one of the types of sedimentary rocks, and this type of stone is mixed with silica cement in the construction of heavy structures, and sandstone is composed of quartz and feldspar and contains different colors such as red, brown, yellow, and others.

This is due to the presence of iron oxide and silica within the sandstone. It is also not suitable for building facades, but can be used in river walls, foundations and bridge walls.

marble
Marble is a very strong metamorphic rock, as limestone is subjected to intense pressure and heat, which turns it into marble. It also features its ability to polish and cut easily and is available in white and pink
