LIMITATIONS TO FLY ASH USE IN BLENDED CEMENTS
The use of blended cements appears to present an attractive alternative to the use of pure portland cement from the standpoint of energy conservation. One of the materials most suitable for use with portland cement in blended cement manufacture is fly ash since it is generated as fine particles and requires little or no processing prior to its introduction into the cement manufacturing process. The limitations of the current specifications covering blended cements along with the need to develop additional durability and engineering performance data on these materials presents a significant obstacle to their production and utilization. The paper discusses the problem in terms of standard tests for blended cements (such as soundness, resistance to sulfate attack, freeze-thaw durability, etc.), and the present state of knowledge on the subject.
