A further factor is that the clinker minerals produced from an industrial cement kiln are not composed of pure C3S, C2S, C3A or C4AF. Each of these minerals contains some minor components in solid solution in the crystal structure of the mineral and this causes deviation from the composition calculated by the Bogue methodology.
80 percent of the raw material is less than 75 microns. Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The European Cement Research Academy (ECRA) estimates that up to 70% of the power consumed in

clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium
In limestone calcined clay cements (LC3), more hemicarboaluminate and monocarboaluminate is observed, as compared to other blended cements, from the reaction of metakaolin with limestone.

In the clay stone clinker, the liquid phase was thicker and dispersed. The amount of free lime found in the clay stone clinker is less common to the free lime mineral found in the metaphyseal sample (Fig. 6). This shows that the metaphoric clinker is more easily cooked than the clay stone clinker and is a better quality clinker.

Lime Saturation Factor (LSF) is the ratio of the actual amount of lime in raw meal/clinker to the theoretical lime required by the major oxides (SiO 2, Al 2 O 3 and Fe 2 O 3) in the raw mix or clinker.It is practically impossible to complete the reaction to , in a reactor like rotary kiln, therefore there will always be some unreacted lime (CaO f) known as free lime.
The main factors affecting clinker reactivity and PSD. Clinker mineralogy and nodule size depend largely on the feed composition and the amount, distribution and nature of the melt phase formed in the burning zone. The clinker melt promotes the reaction between belite (C 2 S) and free lime to form alite (C 3 S), so it is critical for …

A summary of the data used in this study is summarised in the discussion below. Unless otherwise mentioned, the composition of LC3 is assumed to be 50% clinker, 30% calcined clay, 15% crushed limestone and 5% gypsum.
Here are some factors to consider when choosing a limestone crusher machine: Type of Material: The type of material being crushed is an important factor in determining the type of crusher to use. Harder materials require more robust crushers, while softer materials require less robust crushers.

In recent years, Limestone Calcined Clay Cement (LC 3) [1], which primarily comprises calcined clay, limestone powder, and cement clinker, has become a focal point in the field of low-carbon binder materials 2, 3, 4.The foundation of LC 3 cement lies in the synergistic interaction between calcined clay and limestone [5], …
To explore the driving factors, on the one hand, the Russia's clinker factor to cement is still very high with 87%, compared to the global average level with 65% 11.
As clinker is the element within cement responsible for the majority of both its cost and carbon emissions, reducing the clinker content (also know as the clinker factor) of cement has the dual benefit of lowering both the cost of its production and its environmental impact.
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
Limestone calcined clay cement (LC 3) is a promising material for producing cement with low CO 2 emissions and properties similar to, or superior to, those of Portland cement (PC), but at 50 % clinker content (LC 3-50).In many applications, lower strengths than PC are acceptable, opening new opportunities to develop suitable LC 3 …

The use of limestone powder to replace part of the cement clinker to produce Portland limestone cement (PLC) has become increasingly popular. Portland limestone cement is popular for three reasons. 1) When burning to form cement clinker, it consumes a lot of energy and releases a lot of carbon dioxide.

The amount of clinker in cement, known as clinker factor, determines the CO2 footprint of cement. In OPC, clinker factor is ~90 per cent thus, it has a carbon footprint of around 800 – 850 kg/MT of cement. When clinker is replaced with SCMs, the CO2 emissions are reduced as SCMs don't have embodied carbon emissions.
The basic ingredients for portland cement consist of limestone, sea shells, marl, or chalk, that provide the calcareous components; clay, shale, slate, or sand, to provide the silica and alumina; and iron ore, mill scale, or similar material to provide the iron components.
