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 1400C-1500C in the rotary kiln.
The most common cement in use is Ordinary Portland Cement (OPC, Type 1). This type of cement is generally used when it is not likely to be exposed to S04, either in soil or in groundwater. It may contain free lime (CaO) but this is most often hydrated to Ca(OH)2. The interaction with S04 is mainly with the cement component C3A to

Pressed pellets of cement raw meal sample milled with different grinding aids (graphite, aspirin and lithium borate) were subjected to XRF. Graphite produced better particle size uniformity with a corresponding standard deviation that made quality control of raw meal easier and better than aspirin and lithium borate. X-ray fluorescence (XRF) analysis utilizes particle size which is resulted

Aug 27, 2015The differences between ordinary cement lime are as follows: The cement can be used under conditions and circumstances which are not favourable for lime. The cement, when converted into a paste form, sets quickly. The colors of cement and lime are different. When water is added to the cement, no heat is produced and there is no slaking action
Cement composition is based upon their customer's requests, each requiring a different elemental chemistry in recipe. Here are the five stages of cement production and the steps to maintain consistent raw material quality with minimal chemistry deviation, from quarry to silo to customer.

Jun 09, 2010Portland cement concrete is prone to drying shrinkage cracking. It is susceptible to attack by sulphates and has an undesirable reaction with certain aggregates (ASR). Generally, when one accelerates the gain in strength of portland cement concrete through finer grinding or chemical additives, there is a significant increase in drying shrinkage.
