Triethanol amine and ethylene glycol are used as grinding aids for Ordinary Portland Cement (OPC). Standard water of consistency, Blaine area, initial and final setting times and compressive strength are tested for OPC. The phase composition and microstructure of the formed hydrates are tested using DTA/TG and SEM techniques.

cement (PLC) in presence of different dosage of propylene glycol (PG) and commercial grinding aid (CG) after grinding for 45 minutes. For OPC mixes, presence of grinding aids shows higher values of Blaine areas than the control mix. Beside, PG offers better grinding aid performance than the commercial grinding aid (CG). Moreover, GI

The rate constant for the vapor-phase reaction of diethylene glycol with photochemically-produced hydroxyl radicals has been reported as 3.0X10-11 cu cm/molecule-sec at 25 °C (1). This corresponds to an atmospheric half-life of about 17 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm (1).

Cement Grinding Aid Mechanism in VRM. Benefits of Cement Grinding Aid. CGA reduces the inter-particle attractive forces of cement which causes agglomeration of cement grains. CGA are adsorbed on the newly created surface, neutralising electrical charges and thus reducing their tendency to re-agglomerate. Hence, the cement grains show a lower ...
