Abstract
This research aimed to develop a better method of erecting internal partition walls for the Jamaican housing industry. An interlocking concrete block wall unit was considered appropriate because it used local materials and required semi-skilled labor to erect.
A timber mold was made to manually produce the 4 x 4 x 8 inch block. The concrete mix used had a cement to aggregate ratio of 1:7.5 and a sand to gravel ratio of 1:2 and a water cement ratio of 0.753. The average compressive strength of the block determined after three days was 351.56 psi. This translates into an expected final 28-day strength of 878.9 psi.
The blocks interlocked satisfactorily with movement up to 3/16 inch. With tighter controls in mold design it would be improved. The blocks as a walling system can be adjusted to accommodate electrical outlets and vertical reinforcement, which increases its application. Further development with a steel mold along with automated production would increase its market potential.
