High Strength Concrete of High Flowability With Large Amount Addition of Fly Ashes

摘要

In this paper, various high strength concretes of high slump with large amount of fly ashes (HSFC) were made using fly ash of high quality and superplasticizers. The effects of fly ash content on flowability, pumpability and compressive strength of concrete were studied. On the basis of test results, the binding efficiency coefficient of fly ash (K) and admissible maximum amount of fly ash addition to concrete were suggested.
