increase the speed of motor after a reaction temperaturę of about 60°C has been reached.

2.4. Expression of results

Plot the measured temperaturę values as a function of time to generate the wet slaking curve as shown in fig. 2. The slaking reaction of the limę is assumed to be 100% complete at the time whem maximum temperaturę has been reached.

Fig. 2. Wet slaking curves for different activity limę REPORT

-    give the methods of analysis, name and number of analysed materials, used reagents, and quantity of the samples

-    for active MgO and CaO:

calculate results and specify sort of examined limę comparing with the table 1,

-    for time and temperaturę of slaking

temperatures which have been reached every minutę,

time and temperaturę, kind of limę (on the base of time of slaking) and wet slaking curve.

for example: 69/23/7 limę II 69 - temperaturę of slaking 23 - time of slaking 7 - time when 60 has been reached.
