ABSTRACT: This work has presented the evaluation of the compressive strength of hybrid clay bricks from
interlocking brick making machine. The mixture of clay and cement at varying proportions
was loaded into the mould compartment, mechanically rammed and hydraulically controlled.
The raw clay was sourced from Ilesa and Akure in the south-western part of Nigeria. The
results showed that when the cement content was 6%, the highest compressive load and
energy at break were obtained in hybrid bricks from both Ilesa and Akure samples. However,
the optimum service performance under compressive loading was attained at 6% cement in
Ilesa hybrid bricks. Ilesa hybrid bricks possess better reliability and workability under
loading than the Akure bricks.
