ppt on fly ash by Sumit Suman.pptx Fly Ash Concrete 11 ENVIRONMENTAL BENEFITS Use of fly ash in concrete imparts several environmental benefits and thus it is ecofriendly. It saves the cement requirement for the same strength thus saving of raw materials such as limestone, coal etc required for manufacture of cement.
Fly ash seems to have a more pronounced effect on the flexural strength than the split tensile strength. When compared to other mix the loss in weight percentage was found to be reduced by 3.99 to 2.84. and compressive strength was reduced when the cement was replaced by 0% to 20% of fly ash.

Fly ash concrete is more likely to provide satisfactory scaling performance if the watercementitious materials ratio does not exceed and the level of fly ash does not exceed about 25 percent. This, of course, assumes an adequate airvoid system is present in the concrete and that proper construction practices are adhered to.
