COAL ASH PROPERTIES amp; IMPACT ON CLINKER QUALITY
The impact of using high CaO flyash (ie Class C ash) in cement is likely to improve the strength development of the PPC due in part to the pozzolanic reaction, but more so since high CaO ashes contain increased quantities of calcium silicates and aluminates, (identical to those found in clinker), which give cement made with these ashes a degree of selfcementing properties resulting in
