Subsequent to a SPIN group meeting in Zanzibar, where a construction maintenance site was visited and technical discussions about the handbook of clean and safe cement and concrete technologies as well as about the final conference ACCTA 2013 were conducted, a two day student training course took place at the University of Dar Es Salaam. Selected Bsc.-, MSc.-, and PhD-Students from Uganda, Rwanda, Burundi, Mozambique, DR Congo, South Africa, and Tanzania attended the courses.
The lectures were opened by Prof. Mtalo, Principal of the College of Engineering and Technology and Prof. Rubaratuka, Head of the Department of Structural and Construction Engineering. The first lecture was given by Prof. Mrema (University of Dar Es Salaam) on alternative cementitious and burning materials for the production of cement. This was followed by a lecture about basics of rheology and the contribution of the construction chemistry to innovation in concrete technology given by Wolfram Schmidt (BAM Federal Institute for Materials Research and Testing). After that, Ryan Bradley (University of the Witwatersrand) gave a presentation about the influence of wind loadings on shell structures. The final lecture of the day was given by guest professor Regina Stratmann-Albert (FH Darmstadt), presenting application rules and examples of shotcrete technology. The day ended with a practical laboratory workshop given by Wolfram Schmidt dealing with problems of packing density and the mode of operation of rheology modifying admixtures.
The second day started with a lecture of Dr. John Makunza (University of Dar Es Salaam) about the design of bridge structures, followed by a presentation of Akindehinde Ayotunde Akindahunsi (University of the Witwatersrand) about the use of starch in cementitious systems. After that Prof. Herbert Uzoegbo explained the technical differences between earthquakes induced by tectonic activity and by deep mine explosions. Prof. Mitch Gohnert (University of the Witwatersrand) questioned the recent didactic approach towards understanding of shear stresses in structural elements and he explained why reinforced concrete failure occurs under tension rather than under shear. The final lecture was held by Renato Rajzer (Institut IGH d.d.) about quality surveillance regulations ensuring the safety of concrete structures.
The students followed the lectures with high interest and enthusiasm, and the two days of courses gave opportunity to all parties to get connected and generate possible future activities and support.
