Composition and distribution

The project's main objectives were to analyse the data obtained during geological exploration and use it to model and predict biological patterns in order to answer the main research questions: 1) Is there a statistical relationship between the environmental parameters and the benthic community composition and morphospecies observed? 2) Can predictive models be developed from this relationship? In achieving these main objectives, the project also developed recommendations for methods that could be applied during geological exploration voyages to maximise the potential use of data collected.

Steel fiber reinforced concrete (SFRC) is a multiple-composite material developed during the early 1970s. In SFRC, short steel fibers are randomly distributed in concrete. Steel fibers can prevent the development of micro-cracks inside the concrete and reduce the expansion and development of the macro-cracks, thus enhance mechanical performance of SFRC. However, there is lack of studies on the influence of flowability of fresh SFRC on the steel fiber distribution patterns and mechanical properties of hardened SFRC.
