Overview

This studentship is a collaborative study between the Schools of Natural & Built Environment and Chemistry & Chemical Engineering at Queen’s University Belfast and Re-Gen Waste. The project aims to develop a robust process of making waterglass (sodium silicate) from various sources and purities of waste glass cullet, especially from waste grades unsuitable for recycling for the glass manufacturing process. It has already been demonstrated by the applicants that the reaction of sodium hydroxide (NaOH) and waste glass cullet at relatively low temperatures >110 °C, results in the product that is mainly sodium orthosilicate, which performs well in alkali activated concretes (sustainable, low-carbon concretes).

The PhD student will work within Prof Soutsos’ group and will collaborate with experienced researchers that will test the produced waterglass in sustainable construction materials, as the activator for three types of cementless products, i.e. autoclaved aerated concrete (AAC) building blocks, normal density blocks and a non-Portland cement based bagged binder. Furthermore, working closely with Dr Swadzba-Kwasny group, the student will explore simple synthetic strategies to upgrade sodium silicate to high added-value silicon-based materials, such as zeolites.

Extensive collaboration between the QUB team and Re-Gen Waste is already going on. The successful PhD candidate will join a talented team of researchers at QUB and will have links to engineers at Re-Gen Waste to drive this cutting edge research. The position is available from 1st October 2021 and it will be for three years.
