Ettringite Formation and the Performance of Concrete

levels within the concrete, from excess sulfates in cement or fly ash, result in an excessive level of ettringite that clogs the entrained air void system. A related hypothesis is that external sources of sulfates, as found for example in gypsum in deicing salts, could increase susceptibility to freezethaw damage. These hypotheses have appeal.

Uses, Benefits, and Drawbacks of Fly Ash in Construction

Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement. This makes fly ash suitable as a prime material in blended cement, mosaic tiles, and hollow blocks, among other building materials.
