    • PROBLEM TO BE SOLVED: To provide long-life paving concrete excellent not only in the development of long-term strength but also in the development of initial strength, and capable of bringing about a traffic opening early from the start of paving work.SOLUTION: The paving concrete is obtained by hardening a concrete composition which contains at least a binding material containing Portland cement with a 2CaO/SiOcontent of 30-40 mass% and pozzolanic fine powder with a BET specific surface area of 5-15 m/g. In the paving concrete, bending strength at age of one day is 3.5 N/mmor higher.

    • 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.
