| 摘 要： | 通过改善常规C60混凝土的流动性、填充性、抗离析性能等工作性能，采用60d龄期及降低其水化热进行C60大体积混凝土内外温差控制和裂缝控制，降低混凝土的粘稠度并提高其抗离析性以保证其自密实性能。经反复进行混凝土相关性能试验，最终试配出60d龄期的各项指标均符合要求的C60高强度大体积自密实混凝土。

| Abstract: | By improving the performance of conventional C60 concrete such as mobility,filling property and anti-segregation etc.,using the concrete of 60d age and reducing the hydration heat in concrete to take the control of crack of C60 mass concrete and the control of temperature difference between internal and external,reducing the viscosity of concrete and improving the anti-segregation performance to guarantee the performance of self-compacting of concrete.By repeating the tests of concrete performance,get the final trial mixture of C60 high-strength massive self-compacting concrete of 60d age which indexes meet the requirement. |
