摘要

本文介绍了一种旨在研究含F类粉煤灰自固结混凝土(SCC)性能的实验程序。使用分离和流动方法评估了混凝土的新鲜状态特性,并对膏体基质的流变性进行了表征,并与先前开发的膏体流变模型进行了比较。此外,抗压强度,氯化物渗透性和模具光洁度进行了评估。研究结果表明,研制一种含F级粉煤灰且在新鲜状态下性能良好的SCC是可能的。此外,粉煤灰的加入减少了高效减水剂的用量,提高了和易性,提高了总体抗氯离子渗透性。此外,还确定了骨料和基质之间的密度差异会影响先前开发的膏体流变模型的结果。

Properties of Self-Consolidating Concrete Containing Class F Fly Ash: With a Verification of the Minimum Paste Volume Method
This paper describes an experimental program that was aimed at investigating the behavior of self-consolidating concrete (SCC) containing Class F fly ash. The fresh state properties of the concrete were assessed using methods of segregation and flow and the rheology of the paste matrix was also characterized and compared with a previously developed paste rheology model. In addition, compressive strength, chloride permeability, and mold-finish were evaluated. The results indicate that it is possible to develop a SCC containing Class F fly ash that is high performing in its fresh state. Furthermore, the addition of fly ash was shown to reduce superplasticizer dosage, increase workability, and increase overall chloride permeability resistance. In addition, it was determined that the difference of densities between the aggregate and matrix influence the results of a previously developed paste rheology model.
