Propylene glycol was added to OPC clinker with percentage ratios; 0, 0.03, 0.04 and 0.05 wt.% of the OPC clinker. PLC was made by replacing 5 and 10 wt. % of OPC with limestone. PG offers better ...
The grinding time of CL/T and CL/G cements was approx. 25% shorter, compared to neat CL cement. In the case of the CH series, the grinding time was 17% shorter for cement with glycol and 22% shorter for cement with TEA, compared to neat cement. Triethanolamine was a more effective grinding aid than ethylene glycol.
