Mar 01, 1989018332It is well known fact that the reaction of fly ash in concrete, only starts significantly after one or more weeks. Until this period the fly ash behaves more or less as an insert material, which only serves as a precipitation nucleus for CaOH 2 and C-S-H gel originating from the cement hydration.
The lower permeability of fly ash concrete can efficiently reduce the effects of efflorescence. Fly ash is used in many countries because of its advantages. There are also some disadvantages of using fly ash in concrete. These pros and cons are described in brief below.The advantages of using fly ash in concrete includes the followings.

Cinder block gardens have recently become very popular, however a risk of heavy metal poisons from Fly Ash within the concrete may pose a serious threat to the health of an organic garden, leeching toxins into the soil and the plants themselves.
The problem though is that natural pozzolans are down the list of preferred SCMs for their chemical properties after silica fume, GBFS and fly ash.
The study reveals that fly ash concrete has better resistance against freezethaw deterioration due to pozzolanic activity of fly ashes that creates more calcium silicate hydrate gel and fills pore spaces, which can effectively reduce the corrosion of the embedded steel reinforcement.
Low-alkali cements as well as fly ash are used today in new construction to prevent such reactions where this problem may occur.
Using varying quantities of fly ash can result in different hues, ranging from buff to brown. Slag use may produce an initial slight bluish or green tint that lightens with time. Generally, a slag-cement mix will be lighter than a straight-cement concrete.

Jan 13, 2015018332Current Practice and Future Trends Fly Ash Concrete Owing to its pozzolanic properties, fly ash is used as a replacement for some of the Portland cement content of concrete. Use of fly ash can replace up to 30 by mass of Portland cement, and can add to the concretes final strength and increase its chemical resistance and durability.
Feb 24, 2014018332One consideration during the construction process is the fact that salt water tends to speed up the setting of the concrete. However, adding 20 percent fly ash will slow the setting and help make the concrete even more effective. Also, the Portland Cement needs to contain lower or less sulfates when used with the salt water.
Oct 20, 2020018332Therefore, appropriate proportioning of concrete constituents is the easiest way to prevent the concrete mixture problems that may come up during the pumping process. The cement-aggregate ratio should not be more than 16, and the wc ratio should be between 0.5 and 0.65.... fly Ash Percentage in PPC Cements.
