Extrusion is a common process used to manufacture different types of ceramic products, for example, face bricks, ventilated walls, floor tiles, special shaped products and many others. Several parameters affect the operation of the extrusion. These parameters include the nature of the raw materials, their particle size, and their plastic behavior, the water content and the additives you use.

A tile’s strength is a numerical representation of how much weight the tile can support before breaking. The results are expressed in N and they may be converted into kg/cm² using the dimensions of each tile. We are going to go over some methods that can be used to determine a tile’s strength.  

Plasticity is the characteristic behaviour of a ceramic material to become permanently deformed after the application of an external force. This property is the most characteristic one in clays, and there are some factors that influence the plasticity and they should be considered in plasticity measurements:
