Rapid cooling of clinker can mitigate the expansion problems, however higher MgO causes ball formation in kiln, increases melt phase etc. and therefore, can disturb kiln operation. Alkalies A part of alkalies Na 2 O and K 2 O combines chemically with clinker minerals, while as the major part remains as water soluble and affects adversely cement strength (28 Day Strength). If alkalies are not ...
