The team designed the fly ash concrete to be pervious, which means water can pass through it to replenish groundwater and to mitigate flooding potential.
HVFA concrete was shown to have better performance compared to low volume fly ash concrete, given the mixture was sufficiently controlled with low water to cementitious ratio and the use of admixture [2-4].
As a whole fly ash concrete is more stable, uniform, dense, less absorptive and less permeable--all factors which improve freeze-thaw durability.
In this study, the adiabatic temperature rise tests were carried out to accurately evaluate the effect of hydration heat on the temperature of fly ash concrete during the curing ages.

Diffusivity of fly ash concrete maybe one order of magnitude lower than plain cement concrete after approximately 2 years and it is predicted that it may decrease to two orders of magnitude lesser after 100 years [29].
* "Successful Marketplace Implementation of Sustainable Ready Mixed Concrete Using Portland-Limestone Cement (PLC)." Holcim (US) Senior Technical Service Engineer Tim Cost tracked wide adoption of PLC and PLC + Class F or Class C fly ash concrete mixes at Mississippi's MMC Materials.

From these results it can be concluded that percentage increase in strength at 91 & 365 days with respect to 28 days strength is much more for fly ash concrete mixture and control mixture.
The fly ash concrete offers a holistic approach that can help us to achieve the goals of meeting the rising demands for concrete, enhancement of concrete durability with little or no increase in cost (in some instances reduced cost), and ecological disposal of large quantities of the solid waste products from coal-fired power plants [9, 11].
