摘　　要：本文利用环氧树脂基材固化处理模拟放射性焚烧灰,并对固化体的物化性能进行了评价。结果表明:固化体均匀密实,孔隙率为0.14%,抗压强度不低于40.74 MPa;固化体经过冻融、浸泡和辐照后,孔隙率略有增加,但体积变化率均低于2%,抗压强度均不低于40.74 MPa;阻燃性试验后,固化体上出现2.88mm的碳化层,质量损失0.08%。可见,环氧树脂基固化体具有良好的物化性能,有望实现对放射性焚烧灰的有效处理。In this paper,the epoxy resin was adopted to solidify the simulated radioactive incineration ash.Meanwhile,the physicochemical properties of the solidified waste were evaluated.The experimental results showed that the cured waste was uniform and compact,with a porosity of 0.14%and a compressive strength of not less than 40.74 MPa.The porosity of the waste increased a little after the freeze-thaw,immersion and irradiation,while the volume change rate was less than 2%,and the compressive strength was still not less than 40.74 MPa.A 2.88 mm thick carbonized layer appeared on the solidified waste after the flammability resistance test,with a mass loss of 0.08%.It could be concluded that the epoxy resin cured body had excellent physicochemical properties and the epoxy resin based solidification technology could be applied to dispose the radioactive incineration ash effectively.
