Study of Leaching and Mechanical Properties for Immobilization of Radioactive Waste

journal of kerbala university, 2015, Volume 11, Issue 3, Pages 76-84

the present work is a study of leaching and mechanical properties of radioactive waste solidified by cementation using ordinary Portland cement produced by Iraqi cement state company with fly ash (fly ash/cement ratio :0.3) , using different radioactive waste loading capacity (5% ,10% ,15% ,20% ,25% solid and sludge wt%) .
The results showed that the compressive strength increases as the waste loading capacity decreases .a comparison was made between leaching of radioactive nuclides from specimens of different loading capacity for the same period of time apart for readings. It was found that leaching proportional with loading capacity

Study of The Possibility of Radioactive Waste Cementation By Different Types of Improved Iraqi Cement

journal of kerbala university, 2015, Volume 11, Issue 3, Pages 65-75

In the present work study of the possibility of radioactive waste cementation by using ordinary portland cement and Sulphate resisting cement obtained from Iraqi cement state company ( AL-Qaim plant) .The solidified samples prepared with different weight (Water/Cement ratio: 0.62 ,0.55 ,0.44) into cubic of length 50 mm .The chemical additives (Fly ash/Cement ratio: 0.2 ,0.3,0.5) and Topflow SP703,SP603 with (1 liter/100 Kg cement).Resulting mixture were stirred for 30 min.The result showed that the maximum compressive strength after 28 days from preparation of specimens when used ordinary Portland cement and increases with chemical additives .
