Use of Poly Vinyl Chloride (PVC) Tape to Increase the Strength of Bamboo

Poly vinyl chloride is suggested to use as confining
material around bamboo to increase its strength. Investigation is
done on PVC confined bamboo by performing tensile and
compressive strength test. Then we compared the mechanical
performance of unconfined bamboo and PVC confined bamboo.
In this research bamboo is also tested for water absorption with
and without PVC tape reinforcement. Later, on these grounds we
also derived adhesive value of PVC tape, which can be used to find
out length of tape required for any percent of increment in
strength of bamboo. Preliminary results of tensile tests,
compressive tests and water absorption test on bamboo (scientific
name Bambusa vulgaris native name chadao bans or jad vala
bans) are presented in this research. As bamboo confined in PVC
is 27.25% more strong in tension and 77.19% more strong in
compression than unconfined bamboo which depicts that bamboo
confined with PVC tape can be a future alternative for steel in
reinforced concrete.
