raw materials required for the cement are easily available. A typical LC3 blend would contain between 40% to 50% clinker, 15% to 20% crushed impure limestone, 30% to 40% of calcined clay and up to 5% of gypsum. It has been seen that clays with around 50% kaolinite content and limestone with as low as 30% CaO content can be used in LC3.

ME's first low-carbon cement plant planned in Oman
According to experts, LC3 is a relatively new type of cement produced from a blend of limestone and low-grade clays found in abundance in many parts of the world, including the Sultanate of Oman. Unlike clinker, which is produced in a kiln heated to temperatures ranging from 1,200 – 1,350 degrees C, calcined clays require …

Limestone and clinker
Cement plants need large, column free buildings for limestone blending, fuel and additives storage, clinker storage and palletizing areas. Geometrica provides cost effective buildings for all these needs with quick construction and low labor requirements. Limestone blending beds typically go from under 70m to over 120m. Longitudinal additives ...
Clinker Grinding Techniques in Cement Manufacturing
Clinker is a critical component in the production of cement and forms the intermediate product during the cement manufacturing process. It can be best described as a nodular material, usually grayish in color, which is produced by sintering limestone and alumino-silicate materials such as clay at high temperatures in a cement kiln.
Better and cheaper cement: Optimising the right clinker …
Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.

CLINKER SUBSTITUTION IN THE CEMENT INDUSTRY
Once it is produced, the clinker is finely ground and mixed with gypsum and normally with alternative constituents (raw materials or by-products) to make cement1. Producing clinker is CO2-intensive. When limestone is converted to clinker, CO2 coming from the carbonates of the limestone is released (these emissions are known as process …
