摘要：
The decom position speed and mechanism ofalite in Poriland cement clinker are stuc’ied by means of op-tical microscopy,EPMA,XRD and chemical analysis.Theresults show that alite in portland cement clinker decompos-es at the maximum speed when the temperature is at 1025～1175℃.It takes about 40 hours for the alite in clinkerburnt in the rotary kiln to completely decompose at 1175℃,and the 68 hours for the alite burnt in RSP-kiln.Thepresence of CaF2 or CaSOgreatly affects the decomposi-tion speed of alite.The former resists alire to decompose butthe latter accelerates is and enables alite to decompose com-pletely within 6 hours or less.
