Description

In the ready mixed concrete producer in Okinawa Prefecture, fly ash exhausted from the thermal power plant in Okinawa Prefecture was slurried. Simulated column specimens were made by concrete using high volume fly ash slurry. And property of strength in structure was clarified. The conclusions are as follows. It was able to be confirmed the concrete using high volume fly ash slurried by 60wt% in the concentration was able to mix by an actual size mixer at ready-mixed concrete plant, and was able to make simulated column specimens by using it. Compressive strength of core concrete cylinder using fly ash content 50kg/m3 or more per unit volume of concrete after the 28th age was higher than standard curing cylinder on the 28th age.
