Concrete Mix Design - National Precast Concrete Association

This is an indication of the extent of the hydration and carbonation of free lime and magnesia due to exposure of cement to the atmosphere. If cement or clinker is older and has been exposed to weather, then the LOI will be higher. High LOI will have a detrimental effect on set time, strength and air entrainment. If the LOI changes on a mill certificate, expect these properties to change along ...

Cement kiln - Wikipedia

grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot gases from combustion of the kiln fuel. Successive chemical reactions take place as the temperature of the rawmix rises: 70 to 110 °C - Free water is evaporated. 400 to 600 °C - clay-like minerals are decomposed into their ...
