Geopolymer cements for radioactive liquid organic wastes

这个博士项目是由绿色CDT和欧盟PREDIS联盟共同资助的，并将受益于参与这两个研究/行业联盟的世界领先活动。该项目的技术重点是开发、表征和验证用于固定化放射性液体有机废物的硅酸铝“地聚合物”水泥。这些废物在许多情况下无法通过传统的胶结工艺进行有效处理，但对大地聚合物水泥的化学、微观结构和技术特征的分析表明，存在一个非常重要的机会来设计和定制这些水泥，以实现出色的固定性能。将通过与英国和国际行业合作伙伴的参与来确定需要新的固定方法的废物，并将设计地质聚合物基质化学和微结构以匹配关键的废物流。废旧材料的性能将在新鲜和硬化状态下进行表征，并将定义观察到的工程特性的科学基础。

This PhD project is co-funded between the GREEN CDT and the EU PREDIS consortium, and will benefit from participation in the world-leading activities of both of these research/industry consortia. The technical focus of the project is the development, characterisation and validation of aluminosilicate "geopolymer" cements for the immobilisation of radioactive liquid organic wastes. Such wastes can in many cases not be effectively treated by conventional cementation processes, but analysis of the chemistry, microstructure and technical characteristics of geopolymer cements has identified that there exists a very significant opportunity to design and tailor these cements to achieve excellent immobilisation performance. Wastes requiring new routes to immobilisation will be identified through engagement with UK and international industry partners, and geopolymer matrix chemistry and microstructures will be designed to match key waste streams. The performance of the wasteform materials will be characterised in the fresh and hardened states, and the scientific underpinnings for the observed engineering properties will be defined.
