压水堆核电站赤铁矿混凝土X射线屏蔽试验研究

Experimental study on X-ray shielding of hematite concrete in pressurized water reactor nuclear power plant

为了解赤铁矿混凝土与普通混凝土X射线屏蔽效果的差异,对上海某公司提供的赤铁矿进行了性能研究和配合比试配,对赤铁矿混凝土的屏蔽效果进行分析。结果表明,赤铁矿混凝土拌合物和易性为S4级时,混凝土密度、强度、密度均匀性仍然良好;赤铁矿混凝土的屏蔽效果良好。

In order to understand the difference of X-ray shielding effect between hematite concrete and ordinary concrete,this paper studies the performance and tests the mix proportion of hematite provided by a company in Shanghai,and analyzes the X-ray shielding effect of hematite concrete.It is proved that the shielding effect of the concrete is good,and when the workability of hematite concrete is adjusted to S4,its density,strength and density uniformity are still good.
