Earth has been a traditional building material to construct houses in Africa. One of the most common techniques is the use of sun dried or kiln fired adobe bricks with mud mortar. Although this technique is low-cost, the bricks vary largely in shape, strength and durability. This leads to weak houses which suffer considerable damage during floods and seismic events. A solution is the use of dry-stack masonry with stabilized interlocking compressed earth blocks (ICEB). These blocks are manufactured by compacting cement stabilized earth in a manual or hydraulic press into a mould and then air dried. The resulting blocks present uniform shapes and higher values of strength and durability. This work presents the work made in the context of the HiLoTec project. It focuses on the experimental campaign of the project to characterize the strength of ICEBs and the behaviour of dry-stack masonry.
