Gypsum-based mortars for outdoor coating were widely used in the past centuries in a number of European countries such as Italy, Spain, Portugal and France. Research on these materials already highlighted that, although gypsum based coatings for outdoor use are generally thought to best suit regions with a dry climates such as the southern European countries, there is historic and archaeological evidence that these mortars were successful used in more wet environments such as the UK and the Monmartre region of Paris (France) were gypsum was used as a construction material since the Middle Age. However, with the introduction of Portland cement in the 19th century, the use of gypsum in construction dramatically reduced, and the related knowledge went lost. Cement is a great construction material but has a large carbon footprint and our society faces the need to reduce its carbon footprint. For this reason alternative binders are now considered viable alternatives to cement for specific applications.
Unfortunately, despite this interest and the long history, because of the limited use and knowledge currently available and the empirical nature of it, there is still a lack of fundamental understanding for some of the physical, mechanical and chemical characteristics of gypsum when is used in external plasters.
This project aims to advance our scientific knowledge of gypsum in construction, by exploring some aspects of its production and use that are not yet fully understood. The research will be based on a review of the literature available and on experimental work with the aim to develop new gypsum-based products to be used in the construction of new buildings.
Please note eligibility requirement:
* Academic excellence of the proposed student i.e. 2:1 (or equivalent GPA from non-UK universities [preference for 1st class honours]) in conservation sciences, civil engineering, materials science, chemistry, architecture and surveying; or a Masters (preference for Merit or above); or APEL evidence of substantial practitioner achievement.
* Appropriate IELTS score, if required.
This project is well suited to motivated and hard-working candidates with a keen interest in the development of new sustainable construction materials and in experimental work within laboratories of civil engineering and/or chemistry. The applicant should have excellent communication skills including proven ability to write in English.
