摘要： PROBLEM TO BE SOLVED: To provide a method for efficiently determining suitability of aggregate for concrete to ultra-high strength concrete.
SOLUTION: The suitability determining method of aggregate for ultra-high strength concrete is as follows. Mortal is compounded under a compounding condition where coarse aggregate is removed from the compound condition during the construction of the ultra-high strength concrete. It is determined that the fine aggregate used for the mortal is suitable for the fine aggregate for the ultra-high strength concrete when the compressive strength of the mortal cured at a high temperature is ≥1.2 times as large as the compressive strength desired during the construction of the ultra-high strength concrete. Using the fine aggregate determined to be suitable, the concrete containing the coarse aggregate is compounded under the compounding condition of the ultra-high strength concrete. It is determined that the coarse aggregate used for the concrete is suitable for the coarse aggregate for the ultra-high strength concrete when the compressive strength of the concrete cured at a high temperature is ≥1.1 times as large as the compressive strength desired during the construction of the ultra-high strength concrete.
