Abstract:High-strength concrete with air-entraining high-range water-reducing admixture, 0.35 water-cement ratio, 148 kg/m 3 unit water content, and about 60 MPa compressive strength, was produced, and the admixture content and sand percentage were varied. The consistency property was measured by the slump test, and the compaction property and segregation resistance were determined by the flow time through an inverted slump cone. An appropriate mixture that balanced these properties relative to the admixture content and sand percentage was determined from the test. The appropriate mixture can be consolidated by using a shorter vibrating time and lower frequency than in the case of ordinary concrete.
