    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.
