Soil is a combination of excellent Minerals and minerals created by weathering and Rock destruction. Soils are divided into two categories, sticky and non-sticky, and have fine or coarse granulation. The most superficial layer is the soil surface, the type of which depends on climatic conditions, the type of primary rock, the activity of living organisms and the geographical area.
Clay is one of the types of sticky soils that is used in construction. This soil is the result of erosion of metamorphic and igneous Rocks and because of its very fine grains, it is also called colloid. The important point in using this material is to choose a quality sample of it. Clay is the best material that can be used to control the temperature of the building.
The use of clay helps to create heat stability in the building. Since houses are built in such a way that hot or cold weather penetrates inside in summer and winter, the use of clay in construction can be very effective in stabilizing heat and cold and controlling temperature.
Clay is used in the production of Construction materials such as bricks, tiles, ceramics, gypsum and soil mortars, lime mortar, mud straw and pottery. The main reason for using this material is its reasonable price, ease of use and slowness.
It is composed of one or more clay minerals (such as kaolinites or smectites), sometimes with small quantities of quartz, metal oxides and organic matter.
