Cementitious Materials; Advanced Performance

Current project

KEYS - Knowledge Exchange for Young Scientists

KEYS symposia series is an initiative for young scientists from countries in Africa and from Germany to enhance their skills in innovative research in the field of cement and concrete construction technology. It targets young postgraduate and postdoctoral scientists and offers the unique opportunity to network with international high profile researchers and industry representatives. It also fosters networking of the young scientists with their peers in an international forum that promotes their role as future decision makers.

The overall objectives of the symposia series will aim at:

Funded by

1st Symposium: 8th – 12th June 2015, Dar es Salaam, Tanzania

Theme
Raw Materials, Quality Control and Maintenance of Cementitious Products

Host institution
University of Dar es Salaam

Summary
The symposium comprised scientific presentations, discussions, networking and workshops. It took place on three days with a 1-day excursion to a construction site. The excursion was managed by Bam International.



There were additional four workshop groups, each mentored by experienced scientists. Issues on the following topics were discussed: Enhanced gender equality in construction, Educational needs and improvement potentials, Bringing knowledge efficiently into practice, and Future strategies for the KEYS symposia. Each group presented their discussion items and results on the last day, followed by a public discussion with the keynote speakers in the panel. The results from these discussions were noted and will be made available to the public.
