Online ServiceConcrete that contains 10% by volume of fly ash should be labeled "high-performance" concrete. High-performance concretes are used where resistance to aggressive environments is required, such as inside buildings or on outdoor surfaces where there may be exposure to sunlight and high temperatures.
Online ServiceConcrete containing more than 50% of fly ash content by mass of the total cementitious materials is considered as High Volume Fly ash Concrete (HVFAC). Fly ash is considered as a hazardous waste due to leaching of toxic substances into the ground water and soil when it is disposed into ponds, lagoons etc or used as a land fill. In India only 25% of the total fly ash
Online ServiceThe high-volume fly ash concrete, HVFAC, could be defined as any concrete mix having fly ash content larger than 50 percent of the total cementitious materials content. Due to the availability of fly ash in large quantities globally with low cost, HVFAC could be considered as a solution for the environmental impact of Portland cements.
Online Service01-12-2022· 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.
