摘要
岭澳核电站生物防护用高密度混凝土以重晶石为骨料 ,掺加缓凝型高效减水剂配制而成 ,其干密度大于3500kg/ ,28d圆柱体抗压强度大于35MPa。在墙体局部1:1重混凝土浇筑模拟试验的基础上 ,制定了合适的重混凝土施工工艺 ,并在现场实际施工中严格控制。
The high density concrete for protection are composed of barite and retarding high range water-reducing admixture in LING-AO nuclear power plant.The dry density more than3500kg/and cylinder strength at28days more than35Mpa.On the basis of simulation test,appropriate construction techniques is established and controlled strictly in site.
