| Summary: | This paper investigates the compressive strength and flexural strength
of biomass fibre-reinforced concrete slab. The main objective of this
study is to examine the effect of biomass aggregate and fibre glass on
the concrete slab strength. The biomass aggregate is used to replace
the natural aggregates. A total of 36 slab samples (250 mm x 600 mm
x 50mm thick) and 36 numbers of 150 mm cube samples containing
0%, 30%, 60% and 100% biomass aggregate were prepared. The Eclass
fibre and Supracoat SP800 were added to increase the strength
and to achieve the required workability. All the samples were cured in
water with room temperature and tested at the age of 7, 14 and 28
days respectively. The result showed that cube specimens containing
30% biomass aggregate achieved minimum strength for structural use
of 15 MPa at 28 days. The flexural strength for slab specimens
containing 30% biomass aggregate, Supracoat SP 800 and fibre glass
gained higher strength compared with control specimens. The 100%
biomass slab achieved 88% of the control specimen strength. The
workability is between 150 mm to 170mm slump which can become
self-compacting biomass aggregate concrete. The density of the
specimens was reduced 20% for cube and 28% for slab compared with
control specimens. From the finding, it can be concluded that the
biomass aggregate has good potential as aggregate replacement in slab
construction combine with the use of glass fibre and superplasticizer.
However, more research needs to be carried out to verify it. |
