synergistic and environmental benefits of using cement kiln dust with slag and fly ash in cemented paste tailings (thesis format: integratedarticle)
Fly ash cement is generally preferred for masonry, plastering, tiling, and waterproofing works. In these works, strength is not the major criteria. It has slower rate of heat of hydration which makes it less prone to cracks; and also reduces the shrinkage. Fly ash cement has better workability and finishing.
