焚烧灰造粒水泥玻璃固化体抗浸出性能研究

LEACHING PERFORMANCE OF CEMENT GLASS SOLIDIFIED FORMS OF INCINERATION ASH PELLETS

对焚烧灰造粒水泥玻璃固化体的抗浸出性能进行了研究,研究内容包括焚烧灰造粒水泥玻璃固化体的抗浸出性能和水泥玻璃净浆固化体的抗浸出性能。结果表明,在焚烧灰造粒水泥玻璃固化的基础配方(硬化剂,30%;水玻璃,66%;水泥,3%;外加剂,1%)上制备的焚烧灰造粒水泥玻璃固化体和净浆固化体的抗浸出性能好于水泥固化体的国家标准规定的要求,对于核素85Sr和134Cs,第42天的浸出率均≤1.5×10-4cm/d,累积浸出分数均小于6.23×10-2cm。

This paper mainly describes study on leaching performance of cement glass solidified forms of incineration ash pellets, which includes that of the cement glass solidified forms of incineration ash pellets, and cement glass solidified forms. The testing results indicate that the leaching rates of both ^134Cs and ^85Sr from the cement glass solidified forms of incineration ash pellets and cement glass solidified forms are less than 1.5 × 10^-4cm/d on the 42nd day,which are far below regulatory limits of national standards.
