Recently, the function which in reinforced concrete structure comes to be demanded becomes diversification to follow and the High-Fluidity Concrete is demanded, also the research is actively advanced. From test of this research, the study of High-fluidity concrete using the fly-ash is necessary. Because of the result, it will be able to interpret the relationship with of replacement
ratio of the FA and compressive strength with Exponential function. When it will be caused by with this function and the fly-as replacement ratio is same, it is judged with the fact that it will be able to forecast the compressive strength which it follows in the W/B which is various. Constructing the fundamental data which is necessary to a High-Fluidity Concrete mixture plan in
objective, It adds the High-Range Water Reducing Agent and uses the fly-as the High-Fluidity Mortar which it manufactures, it fixed quantity analyzed the Rheology and the quality of the strength. The fly-as with the water relationship does a ball bearing action without, liquidity improvement but, when the fly-as of vast quantity is replaced, it delays a hydration reaction and the possibility the fact that the strength decreases it was.
