An interesting application of the determination of acid by iodometry is proposed for the determination of free lime in clinker and cement free lime in the sample is first extracted with nonaqueous ethylene glycol at 70 c for 15 minutes the filtered suspension is reacted with a known excess of hydrochloric acid the excess acid is determined by iodometry the proposed method is better than.

hai normally free lime calcium oxide is present in clinker whereas in the cement a major portion of it is present as calcium hydroxide this is due to the fact that during the process of hydration it absorbs the water either from the gypsum moisture content or from the high temperature developed during the process of grinding the important requirements which a cement should fulfill.

Cement manufacturers therefore even avoid impurities that cause such effects like free lime 2114 115 for similar reasons the expanding cements used in civil engineering applications.

considering the fact that free calcium oxide content is an important parameter to evaluate the quality of cement clinker it is very significant to predict the change of free calcium oxide content through adjusting the parameters of processing technique in fact the making process of cement clinker is very complex therefore it is very difficult to describe this relationship using the.

Free lime analysis concentration of free lime in this sample was about 2 wt gure 8 in general free lime quantication is realized with a standard method by using a calibration curve therefore peak area method is often chosen for more accurate result of free lime content figure 8 analysis of sample for the determination of free.
