Recently the study on high flowing which has high workability and self-compacting is being proceeded actively in the university and corporative laboratory. The new kinds of cement as changed by its chemical composition and high range water reducing agent enhancing the workability of concrete having been developed, keeping pace with this tendency.
The purpose of this study is aimed for investigating the rheology property and fluidity of cement paste, by changing the substitutional ratio of an admixture, additive dosage of Naphthalene Sulphonate high-range water reducing agent. from result, the fluidity and rheology of paste were different according sorts of powder and additive dosage of agent.
