Portland Pozzolana cement is manufactured either by inter-grinding Portland cement, Clinker, gypsum and fly ash obtained from thermal power plants, or by intimately blending OPC and fly ash. The percentage of fly ash in PPC permitted by IS: 1489 varies from 15 per cent (minimum) to 35 percent (maximum).
The amount of fly ash in mortar or concrete can thus be increased. Other features such as tightness, permeability to chloride ions, etc. are also improved. According to the author, in case of an industrial scale, finer milling of cement clinker (cement) is more preferable solution for the production of fly ash cement than grinding fly ash.
The grinding process has become widely used to improve the fineness and performance of fly ash. However, most studies focus on the particle size distribution of ground fly ash, while the particle morphology is also an important factor to affect the performance of cement paste. This article aims at three different kinds of ground fly ash from the ball mill and vertical mill, and …
