The density of bricks or weight per unit volume depends mostly on the type of clay used and the method of brick molding (softmud, Stiffmud, hardpressed etc.). In the case of standard bricks, density varies from 1600 kg/cubic meter to 1900 kg/cubic meter. A single brick (19 x 9 x 9 cm) will weigh between to kg. depending upon its density.

How porcelain is made

Although the composition of clay varies depending upon where it is extracted and how it. To make porcelain, the raw materials—such as clay, felspar, and silica—are first crushed using jaw crushers, hammer mills, and ball mills. After cleaning to remove improperly sized materials, the mixture is subjected to one of four forming processes ...

 · Burnt clay bricks are basically manufactured by burning (at high temperature) of processed clay. Clay minerals experience irreversible changes imparting strength to the brick at the cost of highenergy input. Here, conservation of energy as well as clay mineral resources are important from the environmental angle.

Clay

Clay is a type of finegrained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or lightcoloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour ...

octahedra. The process of replacing one structural ion for another of similar size is referred to as isomorphous substitution. This replacement represents the primary source of both negative and positive charges in clay minerals. For example, the substitution of one Al3+ for a Si4+ in the tetrahedron results in a gain of one negative charge.
