摘要： PROBLEM TO BE SOLVED: To reduce self-shrinkage occurring in superhigh strength concrete at a low cost. SOLUTION: A method for reducing the self-shrinkage of the superhigh strength concrete comprises substituting an amount of ≤30 vol.% of coarse aggregate for artificial lightweight aggregate and blending an expansive additive in an amount of 30 kg or less per 1 m 3 concrete and/or a shrinkage-reducing agent in an amount of ≤4 wt.% based on a unit binding material, in blending of the superhigh strength concrete having a compressive strength of >100 N/mm 2 . By the method, the degree of the self-shrinkage of the superhigh strength concrete can be suppressed to ≤0-600 μm/m at the material age of 91 days. An artificial lightweight aggregate having a water absorption rate of >5 to 20%, a crushing strength of 1,000-2,000 N, and a density in oven-dried condition of 1.4-2.0 g/cm 3 is used.
