Uses, Benefits, and Drawbacks of Fly Ash in Construction

Feb 17, 2019 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. When used in concrete mixes, fly ash improves the strength and segregation of the concrete and makes it easier to pump.get price

Using Fly Ash in Concrete Precast Concrete

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.get price
