Abstract
The usability of marble as an additive material with clay in industrial brick has been investigated.
Marble was collected from the marble deposit located at Igbeti (latitude 80 45l longitude 40 8l E.), and the red clay was collected at University of Ilorin, Ilorin (latitude 80 32lN and longitude 4034l E), both in Nigeria. Marble and Clay were
processed for the preparation of the composite. The two materials were mixed in varying proportion of marble, ranging
from 0 wt. % to 45 %. The mixture was made into bricks with size 6.0 x 7.0 x 2.0 cm. Ten sample bricks of different
marble composition were prepared. These bricks were compressed and heated at a temperature of 950 0C for 2 hours.
Water absorption and thermal conductivity tests were carried out on the samples. It was observed that the amount of
marble added had positive effect on the physical and mechanical strength of the produced brick. The results also show
that increase in percentage of marble will be of good advantage in keeping the house warm during raining season as
observed from the thermal conductivity test.
