Studies of mechanical properties of treated bamboo

Abstract

Steeping method was used for treating bamboo by using Boric acid Borax, Copper Chrome Boron and Cashew Nut Shell Liquid.Treatment was carried out for 14 day. After treatment, quality evaluation of bamboo was done by cutting bamboo in sample size of 61 cm (2') and exposing them to environmental condition. Mechanical properties of 61 cm (2') bamboo (30.5 cm (1') buried in soil and 30.5 cm (1') above soil were determined by using universal testing machine .After preservation time of 14 days it was observed, out of 20 lit of sample, 10 lit Boric Acid Borax liquid, 5 lit of Copper Chrome Boron liquid was absorbed by bamboo and cashew nut shell liquid was not absorbed by bamboo specimens. It was observed that for the tensile strength for bamboo treated with Boric Acid Borax, Copper Chrome Boron and Cashew Nut Shell Liquid was 38.20 N/mm 2 , 30.69 N/mm 2 and 8.03 N/mm 2 for under soil and 48.09 N/mm 2 , 39.09 N/mm 2 and 9.35 for over soil sample and compressive strength was 5.04 N/mm 2 , 4.02 N/mm 2 and 0.39 N/mm 2 for under soil sample and 5.17 N/mm 2 , 4.87 N/ mm 2 and 0.58 N/mm 2 for over soil sample.
