contain particles covered in a kind of melted glass. This greatly reduces the risk of expansion due to sulfate attack, which may occur in fertilized soils or near coastal areas. Class F is generally low-calcium and has a carbon content less than 5 percent but sometimes as high as 10 percent.

WHY Fly Ash
Fly ash is a pozzolan for concrete, consisting of the “finely divided residue that results from the combustion of ground or powdered coal” as defined by ASTM C 618. A pozzolan, as defined by ASTM, reacts chemically with calcium hydroxide produced by the hydration of portland cement to form additional cementitious compounds.
Types of Fly Ash
Class F Fly Ash
Class C Fly Ash
is typically composed of high-calcium fly ashes with a carbon content of less than 2 percent.
PRODUCT DESCRIPTION
Class F fly ash significantly increases the ability of concrete to resist attack from sulfates in soil or ground water. Additionally, Class F fly ash has been proven through extensive research and field experience to be highly effective in mitigating the deleterious effects of expansive alkali-silica reactions (ASR) in concrete. It is produced from the combustion of pulverized bituminous or lignite coal.
WHEN CORRECTLY PROPORTIONED,
concrete that contains fly ash can have equivalent or greater 28 day, compressive strengths when compared to plain portland cement concrete. Due to the pozzolanic reaction, fly ash concrete will continue to gain strength beyond 28 days, exceeding that of plain portland cement concrete
MAJOR BENEFITS OF FLY ASH
• Cost-effective substitute for Portland cement
• Easier placement
• Reduces water requirements
• Improves pumpability
• Improves durability
• Improves finishability
• Environmentally friendly
• Low emboded energy
APPLICATIONS
Class F fly ash can be used as a pozzolan in virtually any concrete application.
When correctly proportioned, Class F fly ash will add many benefits such as increased strength, increased durability and reduced permeability. Class F fly ash is particularly beneficial in high-performance concrete applications where high compressive, strengths are required or where exposure conditions demand highly durable concrete. Class F fly ash is also very effective at mitigating problems associated with alkali-silica reactions. In mass concrete placements where low heat of hydration is required, Class F fly ash is advantageous in controlling temperature rise.
QUALITY & SPECIFICATIONS
Class F fly ash that is provided for use in concrete applications will meet or exceed the performance requirements of ASTM C 618. To ensure compliance with ASTM C 618, our on-site and central quality control laboratories carefully sample and test the fly ash according to the requirements of ASTM C 311. In addition, independent commercial testing laboratories provide compliance testing.
