Extraction of free lime in portland cement and clinker by ...

Free lime in portland cement and clinker has been determined by extraction with hot ethylene glycol. Our determinations show that times of 5–10 minutes and temperatures of 80–100°C are adequate. This method is as accurate as the ASTM method and has the distinct advantage of simplicity and rapidity.

The Effects of Ethylene Glycol on a Cement-Based ...

Apr 10, 2009 · When ethylene glycol (EG) is solidified with cement, the EG appears to occupy at least 3 different kinds of sites, characterized by differing extractability. Gross alterations of the morphology of the cement matrix do not become apparent until rather large amounts of EG (EG/cement = 0.1 by weight) have been added to the hydrating cement mixture.

What is Ethylene Glycol? - americanchemistry

Ethylene glycol is a chemical commonly used in many commercial and industrial applications including antifreeze and coolant. Ethylene glycol helps keep your car?s engine from freezing in the winter and acts as a coolant to reduce overheating in the summer.
