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.

该博士项目由 GREEN CDT 和 EU PREDIS 联盟共同资助，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用于固定放射性液体有机废物的硅铝酸盐“地质聚合物”水泥的开发、表征和验证。在许多情况下，传统的胶结工艺无法有效处理此类废物，但对地质聚合物水泥的化学、微观结构和技术特征的分析表明，存在非常重要的机会来设计和定制这些水泥以实现优异的固定性能。将通过与英国和国际行业合作伙伴的合作来确定需要新固定途径的废物，并将设计地质聚合物基质化学和微观结构以匹配关键废物流。废弃材料的性能将在新鲜和硬化状态下进行表征，并将定义所观察到的工程特性的科学基础。
