High flowing concrete has not spread whole in the normal concrete structure, because it requires special quality control technique. And recently owing to the lack of natural resources and reinforcement of environmental standard, the construction cost of cement is increased rapidly. Also remicon industry has gone through various economical difficulty as the manufacture cost of concrete is increased. So, the purpose of this study is to evaluate the qualities of middle fluidity concrete using the fly-ash and portland blast-furnace slag cement in order to decrease the amount of cement and resolve the problem of the quality control of high flowing concrete and the manufacture cost. The results of this study show that it reduce the amount of addition of superplasticizer and develope properties of concrete to the use the fly-ash and portland blast-furnace slag cement.
