Clement Egenti a Senior Lecturer (Volunteer) in the Department of Architecture, University of Rwanda, and served under the Technical Aids Corps Program of the Nigerian government to the government of Rwanda. His home Institution is Auchi Polytechnic, Auchi, a place where he served for over two decades as a lecturer in the Department of Architectural Technology. A member of the Nigerian Institute of Architects and a Ph.D. from the University of Wolverhampton (United Kingdom) with a specialization in Architecture, Sustainable materials and housing, Egenti has served as the Head of the Department of Architectural Technology at Auchi Polytechnic and Auchi Nigeria. Egenti also served as the Director of Physical Planning and Dean of School of Environmental Studies at the same Institution.
Baked clay bricks (Impunyu) is the dominant wall construction material in Rwanda. Clay deposits in the country’s lowlands are utilized for baked clay bricks. Despite the ongoing campaign, the use of wood by some local brick producers is unfriendly to the environment. Recent research has called for alternative methods in order to reduce the cost and impact on the environment. Earlier efforts with compressed earth blocks were saddled with weight and a substantial use of cement for good surface texture and adequate resistance against surface erosion. This research explored the potentials of using an appropriate dose of clay (from Muhanzi), volcanic light aggregate (Amakoro, (from Musanze)), and cement to produce unbaked shelled compressed earth blocks (SCEB). SCEB is a compressed earth block with an outer shell and inner core of different cement content or materials, compressed into a unit block. The result is a masonry unit with a higher surface resistance, durability, and desirable architectural effect produced with a 60% reduction in cement content. A weight reduction of 12% was achieved with an optimum content of 33% of the volcanic lightweight aggregate. A cost reduction of 25% was recorded over conventional compressed earth brick walls and a 54% over sand-cement block walls. Possible future trends were also identified with appreciable prospects in earthen architecture.
