The Future of Fly Ash in Concrete CarbonCure
Dec 01, 2020 Fly ash, sometimes called flue ash, has been a popular supplementary cementitious material (SCM) since the mid-1900s. Years of research show that fly ash can decrease concrete’s carbon footprint—and its cost—while increasing its strength and workability. For most concrete producers, fly ash is an important ingredient in concrete mix designs.

Using Fly Ash in Concrete - Precast
May 08, 2010 The use of fly ash will generally lower the heat of hydration in comparison with mixes using only portland cement. Fly ash in concrete may also lead to lower early age strengths. This also varies depending on type of fly ash, and replacement levels. However, fly ash use in concrete has been shown to increase long-term strength.

The Disadvantages of Fly Ash in Concrete Hunker
The structural effects of fly ash may be more critical, but cosmetic concerns also affect its use in concrete. It is more difficult to control the color of concrete containing fly ash than mixtures with Portland cement only. Fly ash also may cause visual inconsistencies in the finished surface, such as dark streaks from carbon particles.

Aug 01, 1999 From the calorimetrical point of view, the effects of solution 4 on the fly ash are almost identical to the effects produced by solution 3. The effect of the activator-fly ash ratio is not significant (the differences in the calorimetry curves are hardly perceptible when that ratio is 0.25 or 0.3); however, calorimetry is very sensitive to the effect of temperature.
