PERFORMANCE OF BITUMEN BOUND MASONRYBLOCK INCORPORATING WASTE MATERIALS
Abstract: Continuous efforts
are needed in
utilizing waste materials
in building industry. This
investigation was intended to use waste materials, namely: steel slag, crushed
glass and coal fly ash for producing Masonryblock, i.e. a masonry building block
bound with bitumen (asphalt). The binder used was bitumen of 50 pen. The materials were
pre-heated at 160 °C for
3 hours before
mixing and compacted using static
compactor at 8 MPa. The
properties of the
blocks evaluated were compressive strength
and creep. In
order to minimize
creep deformation, the samples were heat cured at 160 °C for 24,
48, and 72 hours. Creep test was carried out
by loading the samples
using a cantilever
arm loading equipment
with 1 MPa stress until the creep strain stable. The strain was measured
by means of a 50 mm Demec gauge. It
was found that
the Masonryblock compressive
strength comparable to the
concrete block commonly
used in the
United Kingdom (UK). The sample requires at least 48 hours
curing in order to satisfy creep performance requirement.
