13. CONCLUSION
• Compression: At 5% replacement of marble powder and at addition of 3% of fibre
the compressive strength is like 38.98 Mpa in conventional concrete. For coconut
shell concrete with 5% replacement of marble powder and at 2% addition of fibre
is 36.29Mpa.
• Tension: The cylinders were casted at the same percentage quantities at optimum
percentages for cubes. The values are obtained as 4.69Mpa in conventional
concrete, 3.81 for coconut shell concrete.
• Flexure: The fibre is having the capacity to resist the failure, the values are
5.23Mpa for conventional and 4.34Mpa for coconut shell concrete.
• Impact: fibres are capable of resisting the impact force, the impact values have
shown the better results than normal concrete.
The above values shows that fibre usage is better suited to resist the micro
cracks and bear the impact loads. So the fibre is well suited and this usage can
reduce the solid waste and use of marble powder will decrease the environmental
damage due to Co2.
