ABSTRACT Due to the high cost and environmental problems associated with burnt bricks and

cement blocks used as walling materials, cement stabilized compressed earth

blocks have been introduced as a timely alternative. The design parameters which

deal with aspects such as cement content, fines content, quality control at site and

compaction ratio of the machine have been investigated in order to make this

technology scientifically viable. It is shown that the wall strength and the block

strength can be related so that it could be used in quality control at site. A summary

of the cost analysis is also included in order to show the cost effectiveness of the

compressed earth block technology.
