Within the framework of the SPIN Project, plans were discussed for the conference 'Advances in Cement and Concrete Technology in Africa' that will take place in January 2013. A lecture on application rules for shotcrete construction was given by Prof. Regina Stratmann-Albert who took part in the courses as guest speaker. A short lecture was given by Akindehinde Ayotunde on the use of starch in cement-bound systems. Renato Rajzer talked about standard regulations for quality assurance during site operation. A workshop for an interlaboratory comparison took place with participants from all regions of Africa to test cement according to the standard series EN 196. The Round Robin test comprises the determination of the tensile bending and compressive strengths according to EN 196-1, of the water demand, the initial and final set, and the soundness according to EN 196-3 as well as of the fineness according to EN 196-6.

There they, together with scientists from several other African countries, were to give a course of lectures for Masters and Ph.D. students as well as leading a kick-off workshop for an all-African round-robin test for cement testing. The first stop of the BAM staff was in Zanzibar, where they inspected an on-going a building reinstatement project and discussed plans for the conference “Advances in Cement and Concrete Technology in Africa” (www.accta2013.com) to be held in January 2013. At the international conference in Johannesburg, which is mainly organized by BAM and the University of the Witwatersrand, more than 300 visitors from over 40 nations will come together.
