A ceramic is an inorganic, non-metallic, solid material comprising metal, non-metal or metalloid atoms primarily held in ionic and covalent bonds.Some elements, such as carbon or silicon, may be considered ceramics.
Dispersing agent are used in the mix (sand, stone, cement and water) to lower the use of water and still keeping the same slump (flow) property. This makes the concrete stronger and more impervious to water penetration
Binders are substances that improve the mechanical strength of ceramic bodies so they can pass through production steps, before firing, without breakage. There are a wide variety of binders used in traditional ceramics, including natural products.
