In a study on the use of Alkali-Activated Slag Cement (AASC) as a matrix for the immobilization of simulated China's High-Level Radioactive Waste (HLW), the experimental results show that compressive strength, pore structure, leachability of Cs and resistance to the heat of AASC are better than those of Ordinary Portland Cement(OPC) and High Aluminate Cement (HAC). When simulated HLW loading is less than 25 wt% AASC based waste-forms containing suitable zeolite and condensed silica fume, processed...

In a study on the use of Alkali-Activated Slag Cement (AASC) as a matrix for the immobilization of simulated China's High-Level Radioactive Waste (HLW), the experimental results show that compressive strength, pore structure, leachability of Cs and resistance to the heat of AASC are better than those of Ordinary Portland Cement(OPC) and High Aluminate Cement (HAC). When simulated HLW loading is less than 25 wt% AASC based waste-forms containing suitable zeolite and condensed silica fume, processed by a special technology, exhibit higher compressive strength of 65-100MPa lower porosity of less than 10% and leachabilities of 10~(-5) and 10~(-6)g/cm~2·d for Cs and Sr respectively and these properties are comparable With those of glass. The mechanism of the immobilization of nuclides in AASC based waste-form is also studied.

A new solidification process using AASC (alkali-activated slag cement) to immobilize HLW (high level waste) is introduced in the article. The AASC incorporated with zeolite and condensed silica fume is used as the matrix of solidified product. High temperature and pressure are not necessary in this process. Under a confined volume the pressure caused by hydrolysis of still explosion to densify the matrix of cement. It has high compressive strength, high density, low teachability and high resistance to heat. When the salt loading of HLW in the product is equal to 25 wt% the compressive strength of waste product is 65-100 MPa, the porosity is less than 10%, the leachability for Cs is 10-5 g - cm-2 - d-1 and for Sr is 10-7 g - cm-2 - d-1. The performance of this kind cement is comparable with the vitrifying of HLW, but the process is simpler than vitrifying of waste method. The mechanism of the immobilization and the forms of nuclides in AASC waste product are also discussed.

t was investigated that the Cs leach behaviour of three kinds of cement waste froms, Port-land Cement(PC),Alkali-Activated Slag Cement( AASC)and Alkali-Activated Slag Cementwith Zeolite(AASC with Zeolite), at 293 and 343K. The results show that 28 days cumulativepercent leach of Cs from AASC with Zeolite waste from is one-tenth that from PC waste formand one-sixth to one-fourth that from AASC waste form.The broken line graphes exist be-tween Pt(cumulative leach fraction ) and t(1/2)(square root of time)for these cement waste forms.The diffusion coefficients of Cs calculated form slopes before 3 days are larger than those after 3days for all waste forins. The Cs leachability mainly depends on the compact degree of cementwaste form and concentration of free Cs in the interconnected pores of cement waste form,andthe latter is in inverse proportion to the ability of retarding Cs by hydrates and in proportion to thesolubilities of hydrates.So,the ability of immobilizing Cs in AASC waste form is larger than thatin PC waste form. The leach model of Cs from cement waste from is described.

通过对硅酸盐水泥、碱矿渣水泥以及掺加沸石的碱矿渣水泥固化体在25℃和70℃下Cs ̄+的浸出行为研究发现,掺加30%沸石的碱矿渣水泥固化体28天Cs ̄+累积浸出量仅是硅酸盐水泥固化体的1/10,是碱矿渣水泥固化体的1/6-1/4。几种水泥固化体Cs ̄+的累积浸出分数Pt与t ̄(1/2)作图都呈折线关系,前3天Cs ̄+扩散系数大于后期。Cs ̄+的浸出主要取决于水泥固化体的结构致密程度和固化体连通孔溶液中游离Cs ̄+浓度,而后者则又与水化产物束缚Cs ̄+的能力成反比和水化产物的溶解度成正比。因此碱矿渣水泥固化Cs ̄+的能力大于硅酸盐水泥。同时探讨了水泥固化体Cs ̄+的浸出模型。
