1.概要: 重骨料是指比普通骨料重的骨料,主要用于遮蔽放射线的混凝土。 虽然普通骨料也可用于遮蔽放射线的混凝土,但在有必要减薄蔽遮体厚度时,往往采用单价贵的重骨料配制重混凝土。另外,遮蔽用混凝土如下所述,为了遮蔽住中子射线往往要采用含有有效防护成分或水分的材料作为骨料。 1. Summary: Heavy aggregates are aggregates heavier than normal aggregates and are mainly used to shield radiation from concrete. Although ordinary aggregates can also be used to shield the concrete from the radiation, when it is necessary to reduce the thickness of the shield, heavy concrete of a unit price is often used to make heavy concrete. In addition, the concrete for shielding is as follows. In order to shield the neutron rays, a material containing an effective protective component or moisture is often used as an aggregate.
