A kind of brick. See Dutch clinker, under Dutch.
A very hard burned brick whose shape is distorted or bloated due to nearly complete vitrification
Impurities that melt out of burning coal and collect in the bottom of the fire. The clinker must be removed, to keep the fire clean burning.
is an intermediate cement product made by sintering limestone, clay, and iron oxide in a kiln at around 1,450 degrees Celsius. One metric ton of clinker is used to make approximately 1.1 metric tons of gray Portland cement.
overburned or partly vitrified bricks
a fragment of incombustible matter left after a wood or coal or charcoal fire
a hard brick used as a paving stone
clear out the cinders and clinker from; "we clinkered the fire frequently"
turn to clinker or form clinker under excessive heat in burning
a build up of gunk in the bottom of the forge and sometimes has to be removed as often as once an hour depending on how you maintain your fire
a hard ash formation that is occasionally created when the ash that is present in the burn pot actually begins to melt
The incombustible residue, fused into an irregular lump that remains after the combustion of coal.
Compound produced after cooling raw meal previously burnt to partial melting point at 14500C
Recoverable residue from combustion, especially waste incineration.
The artificial calcium silicate rock formed during the clinkerising process in the kiln and then ground finely to make cement.
Clinker - A local term used for remains of coal that have burned and the surrounding rock that has been transformed during the burning of the coal.
A slag-like material formed in the combustion process when the temperature of combustion exceeds the ash fusion temperature of the fuel.
Red-hot, marble-sized chunks that emerge from the lower end of a (cement) kiln.
A mass of incombustible matter fused together, as in the production of cement or the burning of coal.
The material that emerges from the cement kiln after burning. It is in the form of dark, porous nodules which are ground with a small amount of gypsum to give cement.
An intermediate product used to produce cement. It is produced in cement kilns and consists of dark porous nodules. Synonym: cement clinker.
Powdered cement, produced by heating a properly proportioned mixture of finely ground raw materials (calcium carbonate, silica, alumina, and iron oxide) in a kiln to a temperature of about 2,700oF.
The resulting admixture from burning a combination of limestone with silica, alumina, and iron oxide-containing materials. A lump or ball of the fused material, usually 1/8" to 1" in diameter, is formed by heating cement slurry in a kiln. Clinker, when cool, is ground into a fine powder and interground with gypsum to form cement. See admixture.
In the manufacture of Portland cement, clinker is the solid material produced by the cement kiln stage that has sintered into lumps or nodules, typically of diameter 1-10 mm.
