Abstract :
This research presents the Mechanical
properties of wooddust(sawdust)-Palm Kernel shell
concrete blend. It provides the panacea to the limitation of
Mechanical properties of Sawdust-Palm Kernel shell
concrete blend, which is a concrete composite blend of
cement, sawdust and palm kernel shell (PKS). The
component materials utilized in this study are: Ordinary
Portland Cement, wood dust dust, PKS and water. The
physical index properties were carried out on the
aggregates utilized in this study. Sawdust gave values of
564.28kg/m3
, 0.494, 34.68%, 2.72, 1.0 and 2.79 for the mean
unit weight, mean specific gravity, mean percentage water
absorption, finess modulus, mean coefficient of
curvature(Cc) and mean uniformity(Cu) respectively. PKS
gave relative values of 730.1kg/m3
, 1.67, 12.09%, 5.98, 1.38
and 2.69. Batching of materials was carried out
volumetrically by virtue of the low bulk density and lightweightness of the component material. The blending of the
aggregate materials and binder were manually done. A
total of six(6) cubes measuring 150mm, six(6) numbers of
cylinders measuring 150mm × 300mm and six(6) samples
of solid beams of measuring 150mm × 150mm × 600mm
were produced from blend ratios of 0.9:1:3:3 and 0.9:1:3:4
which corresponds with (water : cement : fine aggregate :
coarse aggregate) to obtain the compression strength, split
tensile strength and bending(flexural) strength
respectively. The above blend ratio and water-cement ratio
were adopted due to the high rate of water absorption of
the constituent materials and to attain the required slump
level and strength for light weight concrete blend. For the
blend ratio of 0.9:1:3:3, the mean compressive strength,
mean flexural strength, mean split tensile strength and
mean static modulus of elasticity were 7.73MPa, 2.76MPa,
1.57MPa and 4.41GPa. The contemporary values for the
blend ratio of 0.9:1:3:4 are 3.84MPa, 2.51MPa, 1.42MPa
and 4.06GPa. The mean Poisson’s ratio ranges from 0.2 -
0.37. The shear modulus ranged from 1.48MPa – 1.84MPa.
The mean flexural strength of wooddust-PKS blend beams
ranged from 2.5MPa to 2.76MPa.
