the fly ash as the sole cementing material (Cross 2005). In addition to providing an indication of the mineralogy and reactivity of the fly ash, the calcium content is also useful in predicting how effective the fly ash will be in terms of reducing the heat of hydration (Thomas 1995), controlling expansion due to alkali-silica reaction (Shehata

Increasing Fly Ash - an overview | ScienceDirect Topics

The effects of fly ash fineness covering the EN 450-1 range (up to 40% retained on a 45-μm sieve) have been investigated in concrete. 311 As shown in Fig. 9.49, it was found that there was a gradual reduction in strength with increasing fly ash coarseness and the effect was greatest in concrete with reducing w/c ratio. Similar behaviour was noted for material from single sources classified to ...
