LightSHIP Inorganic Binder Systems for Innovative Panel Technology in East Africa G. J. G. Gluth, W. Z. Taffese, G. S. Kumaran, H. C. Uzoegbo, H.-C. Kühne
Urban population *projection Urban population in Africa World Urbanization Prospects: The 2007 Revision; United Nations: New York, 2008.
Need for affordable building materials Large increase in urban population e.g., population of Addis Ababa has doubled nearly every decade
Associated problem of enormous pressure on social and physical infrastructures (slums)
Alemayehu, E. Y. PhD Thesis, Norwegian University of Science and Technology, Trondheim, 2008.
Large need for affordable buidling materials to construct housings, public buildings etc.
Magnesia boards Approach in Addis Ababa: production of partition boards from magnesium oxychloride cement
The LightSHIP project Partners:
EiABC / Addis Ababa University

University of the Witwatersrand, Johannesburg
BAM Federal Institute for Materials Research and Testing
German-African Business Association
Addis Ababa African partners Kigali Johannesburg European partners www.google.de/maps
Generation of a continuing scientific partnership in the sector of building materials research
Analysis of problems and possibilities of the participating African countries related to the design, application and testing of building materials
Evaluation of possible approaches to overcome these problems and ultimately to develop new building materials for East Africa
Preparatory tests on available building materials
Development and preparation of follow-up cooperation
Specifications for building materials
Pre-fabricated elements are to be prefered.
optimised fabrication process and minimization of risk of failures
Elements should be easily transportable and easy to assemble.
The materials should be produced with the highest possible fraction of local resources.
Existing know-how in the participating countries should be used.
Artificial stones and partition boards
Lightweight concrete: mix design Superplasticizer: PCE1.38 kg/m³ (0.44% of cement mass) * Blend of CEM I 32.5 R and CEM I 52.5 R (50% each) ** Water which is absorbed by the lightweight aggregates in the first 10 minutes.
