A Study on Properties of Concrete with Dry Fly Ash and Fly Ash Slurry Stored with Stirring Part1 Summary of Experiments and Fresh Properties

摘要

As a previous study, we invented a device to remove unburnedcarbon by Flotation Method. Since the flotation methodimmerses the fly ash in water for treatment, it is necessary toverify the influence of the slurry of the fly ash on the concrete.Therefore, in this study, fly ash from three different sources wasstirred and stored for 1-28 days, and the physical changes of thethree substances stored under this condition were recorded, andthe freshness of the concrete using dry powder was confirmed.And check the usefulness of the slurry.
