以鄂州市含铬渣泥作为主要原料、宜昌页岩为校正原料制备防辐射集料,系统研究原材料的组成、预热制度、温升速率、煅烧制度对防辐射集料性能、矿物组成的影响,成功制备出表观密度高于2．30 g/cm3,抗压强度高于5 MPa,1 h 吸水率低于8％,对0．662 MeV的γ射线线性衰减系数达0．172 cm－1的防辐射集料.
이악주시함락사니작위주요원료、의창혈암위교정원료제비방복사집료,계통연구원재료적조성、예열제도、온승속솔、단소제도대방복사집료성능、광물조성적영향,성공제비출표관밀도고우2．30 g/cm3,항압강도고우5 MPa,1 h 흡수솔저우8％,대0．662 MeV적γ사선선성쇠감계수체0．172 cm－1적방복사집료.
With Chromium slag as main raw material,the shaly of City Yichang as the correction material for the preparation of radiation shielding aggregate,the effect of the composition of raw materials,preheating,temper-ature rise rate,calcination for radiation shielding performance of aggregates and the mineral composition was re-searched.The successful preparation of radiation shielding aggregates whose apparent density was higher than 2.30 g/cm3 ,compressive strength was higher than 5 MPa,bibulous rate for 1 h was lower than 8%,and linear attenuation coefficient achieves 0.172 cm-1 by 0.662 MeV gamma-ray was completed.
