The added limestone in the is modern portland cement and consists of ground clinker, a source of readily soluble sulfates and functional additives. The change is that the specification adds up to 5% limestone. The biggest difference in production is that the limestone is added to the clinker blend before grinding.

1.. IntroductionThe use of Portland limestone cements seems to have many benefits, both technical and economical [1], [2], [3].In addition, the European Standard EN 1971 identifies two types of Portland limestone cement containing 620% limestone (type II/AL) and 2135% limestone (type II/BL), respectively [4].It is expected that the future world production of Portland limestone cement ...

Clinker is ground in a mill with gypsum to produce portland cement. Blending limestone in the cement allows for a reduction in the amount of clinker, which reduces the carbon footprint per ton of cement. In addition to PLCs, the concrete industry is dedicated to develop new technologies that contribute to a greater reduction in overall CO2 ...

In practice, portlandlimestone cement is ground to a higher fineness compared to portland cement. An increase of Blaine in the range of 100cm 2 /g is necessary to compensate for the strength reduction resulting from the addition of 1% limestone. 3.

Full factorial experimental design was applied to evaluate the effect of 5% limestone addition on various properties of cement in relation to clinker type and fineness. Two clinkers, differing only in lime saturation factor (LSF), were used, and cements with two levels of fineness were prepared. The experiment was performed in realscale conditions on a ball mill with a capacity of 15 t/h.
