Use of biomass fly ash for mitigation of alkali-silica ...

Jan 01, 2012  Highlights Use of biomass fly ashes to mitigate the ASR of cement mortars. Cement was replaced (20–30 wt%) by the biomass fly ashes. Accelerated mortar-bar tests were conducted (ASTM C1260/ASTM C1567). This substitution tends to reduce the expansion upon accelerated curing conditions. The blend of biomass fly ash (20%) with metakaolin (10%) is very effective.

Alkali-activation potential of biomass-coal co-fired fly ash

concrete industry is currently the primary user of coal fly ash as a supplementary cementitious material, but co-fired fly ash—which is the main by-product of the co-firing process—is not currently addressed in the U.S. standard for fly ash use in concrete, ASTM C618-12a [3].

Using Fly Ash in Concrete - Precast

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.
