A powder made from silica, alumina, lime, iron oxide, and magnesia which solidifies when mixed with water; this is used as an ingredient in mortar, concrete self levelling solutions etc.


Solid materials made by firing of non-metallic minerals, used in the manufacture of such products as tile, plaster refractories or brick.


A process in which a substance of individual particles comes together to form a coherent mass.


The act or process of pressing together substances either through gravity or applied pressure, which can form a denser substance or cohesive product.
