矿渣掺杂的硅酸盐水泥对放射性泥浆水泥固化体性能的影响研究OA

During the storage of radioactive waste liquid in nuclear facility storage tanks,a large amount of brown radioactive mud sediment is easily formed at the bottom of the tank.Based on this,the influence of slag doped silicate cement on the properties of radioactive slurry cement solidified body is studied.The results show that as the slag content increases,the cement The density of the slurry gradually increases,and the fluidity gradually decreases.The compactness of the cement solidified slurry gradually increases,and the Cement Silicate Hydrogel(C-S-H)gel formed increases.When the slag content reaches 18%,the pressure resistance of the cement slurry solidified body increases.The strength is as high as 20.99 MPa,and the pore size is 0.4 mm.The compactness of the solidified body is enhanced,which greatly improves the leaching rate of the solidified body,providing a reliable basis for solidifying radioactive mud with slag-doped Portland cement.
