The study is propertys analyze such as the paste rheology, yield value and compressive strength etc. with used to the admixture micro powder manufacture high flow mortar, the purpose was the it`s obtain design of mix proportion of the high flow concrete or mix design necessary basic date.
The result is admixture balance rate was highed according to the transposition rate to be good working a ball bearing flexibility.
However, W/B is raised that it judge the unit volume weigh more than rising the flexibility is the huge affect according to the admixture`s transposition rate or addition rate of high range water reducing admixture. A special quality of mortar was according to the admixture transposition rate drop the early-age strength and it raising strength with keep dropping the W/B.
It was reveal that as result of plzzoanic reaction of admixture is low early-age strength and high long-time strength.
The conclude, in the more than variety of the mix condition that the research need about the high-fiuidity concrete of theory design of mix proportion or mix design method.
