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.

摘要： PROBLEM TO BE SOLVED: To provide an artificial lightweight aggregate production process which enables production of aggregate green pellets each having sufficient strength and also, sufficient enhancement of crushing strength of sintered aggregate (the artificial lightweight aggregate). SOLUTION: This production process comprises performing pelletization and sintering by using an aggregate raw material containing >=40 wt.% coal ash, wherein: a water-soluble high polymer and a compound selected from alkali metal carbonates, alkaline earth metal carbonates and compounds each capable of being formed into a chelate compound, are added to the above aggregate raw material; and also if necessary, a surfactant is further added to the resulting aggregate raw material. Thus, in the pelletization, further uniform mixing can be performed to obtain green pellets each having further enhanced strength and in the sintering, constituent particles of such a pellet can sufficiently be fused to each other to sufficiently enhance crushing strength of the resulting sintered aggregate (artificial lightweight aggregate).
