—This paper reported on an experimental program
to research the effect of using blasted copper slag from shipyard
repair and maintenance as replacement of fine aggregates in the
sand-cement brick. 20 cubes of cement sand brick mixtures
were produced with different blasted copper slag ratio ranging
from 0% (for the control mixture) to 60%. All the sand-cement
brick mixtures were tested for their compressive strength,
density and water absorption at day 28 of air curing. There was
a 16.28% improvement in the compressive strength of brick
with 20% replacement of copper slag as fine aggregates in
comparison with control mixture. However, the addition of
higher percentage of blasted copper slag as fine aggregates
resulted in reduction of compressive strength but the density
was increased. Also, the results of water absorption decreased
as copper slag ratios in brick increases. The water absorption
for 60% of copper slag ratio in brick was the lowest absorption
compared to 20% of copper slag to sand ratio in brick. Hence, it
is recommended that 0% to 20% of blasted copper slag may be
used as a replacement of fine aggregates in order to obtain a
good strength and low density of sand-cement brick.
