The reactions at this stage are: 12 CaCO3 + 7 Al2O3 → Ca12Al14O33 + 12 CO2. 4 CaCO3 + Al2O3 + Fe2O3 → Ca4Al2Fe2O10 + 4 CO2. 4 CaCO3 + Al2O3 + Mn2O3 → Ca4Al2Mn2O10 + 4 CO2. Decomposition of remaining calcite: A little amount of calcite remains at this stage and forms free lime for the first time: CaCO3 → CaO + CO2.

When limestone is converted to clinker, CO 2 is released (also known as process emissions). What is a clinker in a coal stove? Clinkers, also known as slag, and in coal fired boilers consist of the noncombustible elements and minerals found in coal that melt and fuse together as lumpy ashes from coal combustion. Clinkers resemble volcanic ash

How do you play clinkers? To play this game, the presenter will draw a clinker chocolate out – students will guess if it is a pink, green or yellow clinker by completing a different action (e.g. hands in the air for pink, hands to the side for green and hands facing down for yellow, or holding up 1, 2 or 3 fingers corresponding to the colour)

A clinker with a higher LSF will have a higher proportion of alite to belite than will a clinker with a low LSF. Typical LSF values in modern clinkers are 0.92-0.98, or 92%-98%. Values above 1.0 indicate that free lime is likely to be present in the clinker.

Limestone (96 wt.% CaCO3) and chalk (74 wt.% CaCO3), provided by the industrial collaborator of the project, were tested, and maximum CaCO3 conversion yields of 49 % and 79 % were recorded, respectively. This is likely linked to the smaller average particle size of the chalk compared with the limestone, resulting in an enhanced contact surface.

Whereas the U.S. standard for portland cement allows for up to 5% of clinker to be replaced by limestone, the standard for blended cement allows for 5% to 15% limestone replacement in PLC (Type IL). The same clinker is used to make portland cement and portland-limestone cement, but there is less of it in PLC.
