<h2 class="heading hide-accessible">Summary</h2>

This project aims to address some of the questions around design and in service performance of Geopolymer Pillar piles and will be underpinned by numerical studies.

<h2 class="heading hide-accessible">Full description</h2>

<p>Geopolymer Pillar is an emerging technology for ground improvement and structural support. The technology has been developed to solve problems caused by weak foundation soil conditions, which may be too challenging to treat cost effectively with conventional ground engineering methods. </p> <p>In addition, as these piles use geopolymers they compare very favourably in terms of carbon emissions with traditional piling methods having cement based binders. As the technology is relatively new, there are many questions left unanswered is relation to its design and modelling. </p> <p>This project aims to address some of the questions around design and in service performance of these piles and will be underpinned by numerical studies. Particular emphasis will be placed on the simulation of the installation processes. This would enable the modelling of the effect of the substantial stresses imparted in the ground as the pile is installed. Aspects related to in-service performance, i.e. reduction of settlement and onset of consolidation processes will be considered in the analysis. While the numerical studies can be developed for a general geotechnical ground improvement application, it is envisioned that the behaviour of the geopolymer Pillar be studied in soft ground. </p>

<h2 class="heading heading--sm">Entry requirements</h2>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

<h2 class="heading heading--sm">English language requirements</h2>

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
