一、引言水泥固化是普遍公认的一种简便易行且源广价廉的固化技术,目前已为世界许多国家采用,并逐步向固化低生热高放废物的方向发展。众所周知,同玻璃固化相比,水泥固化的主要缺点是固化物的机械性能较差、浸出率较高、热导性较差,以及存在可能的辐解问题。这些问题限制了水泥固化的应用范围。本文研究了用聚合物浸渍混凝土(PIC)技术增加固化物的抗压强度和降低固化物的浸出率的可能性。
I. INTRODUCTION Cement curing is generally accepted as a simple, easy-to-use, low-cost source of curing technology. It has been adopted by many countries in the world and is gradually being used to cure low-heat, high-level radioactive waste. It is well known that the major disadvantages of cement curing compared to glass curing are the poor mechanical properties, high leaching rates, poor thermal conductivity, and possible radiolysis problems. These problems limit the scope of cement curing applications. This article investigates the possibility of increasing the compressive strength of a cured product and reducing the rate of solidified product leaching by using polymer-impregnated concrete (PIC) technology.
