20392. Fly ash. Fly ash improves concrete's workability, pumpability, cohesiveness, finish, ultimate strength, and durability as well as solves many problems experienced with concrete today–and all for less cost. Fly ash, sometimes called flue ash, has been a popular supplementary cementitious material (SCM) since the mid-1900s.

Fly ash may be particularly promising as it is a coal combustion byproduct that can be reused in many different contexts, such as construction and pavement. Worrell et al. (2004) identify potential energy savings of up to 20% from deployment of blended cement technologies, and larger carbon dioxide emission reductions.

This is an experimental study which explores the physical, mechanical, and economic factors involved in the production of type CEM II A-B/W cement. In this context, 4 cement additives were used in two different dosages (200 and 800 g/t). Class C fly ash was used for composite cement production at ratios of 5%, 20%, and …

clinker, but with different fly ash sources. While the untreated cement needs a superplasticiser dosage in the range of approximately 0.5-0.8 per cent, the variation can be reduced to about 0.5-0.6 per cent in the case of the treated fly ash cement. Figure 1: strength development of CEM IV/B 32.5 N with 41 per cent fly ash
