Fly Ash Increases Resistance to Freezing and Thawing - Technical Bulletin
Freeze/Thaw Deterioration Begins when water enters voids in concrete. Leaching of calcium hydroxide, producing the hydration of portland cement, provides greater voids for water to occupy, thereby aggravating the rate of deterioration. Upon freezing, this water expands in volume 9%, generating pressures of 30,000 ...

Class F Fly Ash Increases Resistance to Sulfate Attack - Technical Bulletin
Sulfate attack is a two-phased process. Sulfates combine with calcium hydroxide generated during cement hydration to form calcium sulfate (gypsum). The volume of this gypsum is greater than the sum of its components causing internal pressure and expansion, which fractures the concrete. Then aluminate compounds from portland cement react chemically with sulfates and calcium to form a compound ...

Fly Ash for Concrete - Brochure
Power plants fueled by coal produce more than half of the electricity we consume in the United States today. But in addition to electricity, these plants produce a material that is fast becoming a vital ingredient for improving the performance of a wide range of concrete products. That material is fly ash. Fly ash is comprised of the non-combustible mineral portion of coal. When coal is consumed ...
