Abstract: The cement solidification formula is researched for the concentrated liquid, which comes from the evaporation process of some low radioactive liquid waste. In the first, the characteristics of the source terms, such as p H, conductivity, chemistry composition, salt contamination, nuclear species and generational β activity concentration, are inspected and analyzed. And then, the solidified samples are made using the conventional and radioactive reagent separately. Secondly, seven technical parameters such as resist pressure strength, shock strength, resist infusion strength, resist frozen and melt strength, dissociated liquid volume and nuclear species infusion ratio are tested one by one. The experimental data is analyzed and the optimum ratio of the cement and the concentrated liquid is determined as 0.5. At last, the concentrated liquid cement solidified engineering survey is developed according to the formula mentioned above. The study results indicate that the performances of the solidification body satisfy the national criteria. The cement solidification formula could regard as the reference for the concentrated liquid cement solidified.
