About the Project
The goals of this project are to improve the understanding of the fire behaviour of thin-walled CFRP self-prestressed SCC slabs and to define design criteria for fire performance to enable their application in building interiors.
The above objectives require the development of a spalling resistant expanding concrete. Accordingly, the first stage of the proposed thesis will be dedicated to understanding the spalling mechanisms of the current expanding SCC and the subsequent development of a spalling resistant expanding SCC of 75 MPa strength class or higher. Initial experiments have shown that Empa’s current expanding SCC spalls rapidly when centrally precompressed and subjected to an incident radiant heat flux representative of a compartment fire in a building. Therefore new spalling-resistant SCC mix designs will be studied using different admixtures and fibres. Thereafter, a series of self-prestressed SCC slabs will be studied for spalling. An experimental fire test series on thin-walled slabs will be performed at The University of Edinburgh.
A final stage will commence after satisfactory spalling resistance has been achieved by the used self-compacting concretes. Experiments will be designed to understand the high temperature bond behaviour between the UHM CFRP tendons and the novel prestressed SCCs.
This project may include annual multi-week research visits to EMPA Dubendorf; timescales, budget, and student interest allowing.
