A significant reduction of energy consumption can be noticed during the grinding of Portland cement clinker and gypsum by adding a small quantity of a grinding aid (GA) in the range of about 0.02- 0.10 % of the manufactured cement weight inside the cement mill.
Additives may be used between 150 and 500 g per ton of cement. A more thorough investigation into glycerol application on cement clinkers revealed that glycerol can interfere with both the chemical and physical. The studies conducted have concluded that glycerol during the course of grinding alters the particles' surface tension .

A concrete grinder is a finishing tool used to perform the process of grinding and leveling concrete surface to provide a smooth finish. The concrete grinder can be used as surface preparation tool, aggressive coating removing tool and as concrete polishing tool. The basics of concrete grinder, its types and benefits are briefly explained below.
Cement grinding aids are certain surface active chemicals, often polar in nature, adding to the mill in small percentages to improve the performance of the mill. This is because with excellent surface activity can be easily adsorbed on cement particles, and accelerate the grinding of cement particles.
Below chemical regent are normally used as cement grinding aid: three isopropanolamine, ethylene glycol, triethanolamine, sorbitol, diethylene glycol, glycerin, etc. Because of the bad adaptability, stability and imperfect function, single-component cement grinding aid is difficult to
The glycerin (GL) is commonly used as a grinding aid component in cement production, however it can bring poor compatibility between cement ground with it (GL-C) and polycarboxylate superplasticizer (PCE), which causes difficulties to construction. This paper studied the influence and its mechanism of GL on the compatibility between cement and PCE.

{Question} My cement supplier is adding limestone to their cement. Is there anything to worry about? Will I have to reduce the fly ash content I normally use? {Answer} Recently, ASTM C150 was harmonized to meet the AASHTO M85 to allow up to 5% limestone in the cement. The history of limestone in cement is a little checkered, and as a result, there is …
