抄録

The concretes containing large quantity of fly ash with constant portland cement content were produced at the ready-mixed concrete plants, and placed into full scale formworks. Their fresh and hardened properties were measured and discussed.<br>1.At various fly ash content per unit volume, for example 455kg/m3, the concretes which have various flowability, such as medium or high fluidity concrete, were produced easily. And they could be filled smoothly into narrow space of wall formworks with reinforcements.<br>2.The fly ash concretes appeared higher compressive strength from the early age and carbonation resistance than those of the concrete without fly ash.
