Structural clay products , ceramic products intended for use in building construction. Typical structural clay products are building brick, paving brick, terra-cotta facing tile, roofing tile, and drainage pipe. These objects are made from commonly occurring natural materials, which are mixed with water, formed into the desired shape, and fired in a kiln in order to give the clay mixture a permanent bond. Finished structural clay products display such essential properties as load-bearing strength, resistance to wear, resistance to chemical attack, attractive appearance, and an ability to take a decorative finish. In this article the raw materials, properties, and general applications of structural clay products are reviewed. At certain points reference is made to industrial processes employed in the manufacture of structural clay products; for more detailed description of these processes, the reader is referred to the article traditional ceramics. Structural clay products are made from 35 to 55 percent clays or argillaceous clayey shales, 25 to 45 percent quartz, and 25 to 55 percent feldspar.

Clay is a type of fine-grained natural soil material containing clay minerals. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Between one-half and two-thirds of the world's population still live or work in buildings made with clay, often baked into brick, as an essential part of its load-bearing structure. Clay is a very common substance. Shale , formed largely from clay, is the most common sedimentary rock. Silts , which are fine-grained soils that do not include clay minerals, tend to have larger particle sizes than clays.

Structural Clay Products pp Cite as. After preparation of the raw materials with regard to composition and particle size, structural clay products are usually formed in the plastic state. This means that water is added to the raw materials to produce the proper consistency and wet strength. In this process peculiar things happen that create the really unique plasticity of clays. We find that as water is added to dry clay there is as much or more of a change in the properties of the water as there appears to be in the alteration of the clay into a plastic, formable mass. For this reason it is necessary for us to pause here to look at the structure and properties of water before discussing the interactions between clay and water in an attempt to explain plasticity.

Я любил тебя .

Вокруг него бушевала настоящая буря, но в его глазах она увидела смирение. Губы Стратмора приоткрылись, произнеся последнее в его жизни слово: Сьюзан. Воздух, ворвавшийся в ТРАНСТЕКСТ, воспламенился.
