Ceramic tiles waste is generated from
construction sites or factories where they are being
manufactured. In the present construction world, the
solid waste is increasing day by day from the demolitions
of construction. Ceramic products are part of the
essential construction materials used in most buildings.
Construction industry can handle most of the ceramic
waste produced from anthropogenic activities as well
reduce rate utilization of quarried natural resources.
Ceramic floor tiles collected from different location was
dried, crushed and ground by mechanical grinding
machine. The waste generated after grinding was passed
through sieve size of 4. 75 mm. Particle size distributions
was carried out on both fine and coarse aggregate in
accordance to (BS 1377-2:1990), Workability test was
also carried out on concrete. Specific gravity was carried
out on cement, fine aggregate and cement. Concrete
cubes were cast for each replacement (0%, 5%, 10%,
15% and 20%) with water cement ratio (W/C) of 0.5 and
they were cured for 7, 14 and 28 respectively. Water
absorption and consistency test were carried out on
conventional and modified concrete .The result showed
that Particle size distributions of the aggregates were
well graded. The modified concrete exhibit true slumps.
Specific gravity of cement, fine aggregate and crushed
ceramic tile are 2.63, 2.65and 2.50 respectively. It was
observed that 10% at 0.5w/c of replacement has higher
water absorption rate of 1.14% and 5% at 0.5w/c of
replacement has lower water absorption rate 0.88%.
The compressive strength at 28days for modified
concrete (5% and 10% replacement) with w/c of 0.5 were
27.33 N/mm2 and 25.58 N/mm2
compared to control (25
) at 28days.The study concluded that the modified
concrete at 28days, having water-cement ratio of 0.5 at
5% and 10% crushed ceramic tile replacement have
properties as a normal weight concrete.
