The mechanical properties were evaluated to examine the optimum adding amount of AC and UT viscosity agent by mixing two viscosity agent according to the adding ratio. When the ratio of AC and UT viscosity agent was 5:5, It was most suited for high-fluidity concrete with low binders by increasing workability and effect of reducing viscosity.
