| Abstract | The purposes of this study can be divided into two parts. The first part deals with an investigation of using bamboo as a low-cost construction material and previous study on the preservation of timber and bamboo by using different types of chemicals. The second part of this study involves an experimental investigation on the treatment of bamboo in order to improve its durability. Based on the study in the first part, two appropriate preservation methods were selected for testing one species of bamboo (locally called Pai Tong) available in Thailand. The bamboo samples to be used are about 3 years old. Two methods of treatment of bamboo were adopted, namely Boucherie Method and Modified Boucherie Method. The methods selected are based on appropriate technology, i.e. both economically and technologically feasible in rural areas of developing countries. Three types of preservatives have been selected. They are Acid Cupric-Chromate Composition (ACC), Chromated Zinc Chloride (CZC) and Copper Chrome Boric Composition (CCB). Both treated and untreated bamboo samples were tested for their mechanical properties and also for subsequent testings. Finally, a cost analysis of the treatment methods using different types of preservatives was conducted. Test results indicated that among the three types of preservatives used in the treatment of bamboo, the absorption capacities of preservative containing copper chrome boric composition was the highest. With regard to the chemical absorption of the bamboo, no signicant difference was observed when the Boucherie Method and the Modified Boucherie Method were used for the treatment of bamboo in this study. The strengths of treated bamboo samples in general are comparable and slightly higher than those of untreated samples. Based on the cost of treatment, strength and absorption of bamboo, it is recommended that preservative containing acid cupric-chromate composition be used as the preservative in the treatment of bamboo. |
