The objective was to determine their suitability for construction, especially for structural members. Proximate analyses as well as mineral contents were also determined. The moisture content and density of green samples were 155% (dry basis) and 587 kg/m3, respectively. L. secundiflorum had the highest carbohydrate content while C. deerratus had the least. Radial shrinkage and swelling exceeded longitudinal shrinkage and swelling in all the rattan species, suggesting high anisotropism in movement. Moisture content had significant effect (P < 0.05) on the moduli of elasticity and rupture of all the rattan species. The moduli of elasticity of C. deerratus, E. macrocarpa and L. secundiflorum were 3396, 516 and 11 106 N/mm2 respectively. The strength properties of the rattan canes were found to be lower than those of timber species of comparable densities. The physical and mechanical properties of the rattan canes studied were found to be adequate for use as reinforcement in lowly stressed concrete elements, such as frameworks for ferrocement and complex shaped formworks.","PeriodicalId":39305,"journal":{"name":"Journal of Bamboo and Rattan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87009099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The variables studied were adhesive types, grain orientation (parallel-ply or cross-ply) and bonding properties of strips taken from different parts of bamboo culm, i.e. strips taken near the periphery or near the inner layer or a combination of both. Commercially available adhesives, phenol formaldehyde (PF), urea formaldehyde (UF) and melamine urea formaldehyde (MUF), were used to bond the bamboo strips. The bonded specimens were subjected to plywood shear test in both dry and wet conditions. The study showed that PF resin formulation suitable for the production of tropical plywood was found to be most compatible for bonding bamboo strips; nevertheless, a slightly longer press time is required to ensure sufficient curing of resin. All shear strengths and wood failure percentage of the PF-bonded laminates met the minimum requirement of British standards. The bonding properties of UF-bonded laminates achieved the standard only when tested in dry conditions. Hot press parameters employed for pressing the MUF-bonded laminates was not sufficed to cure the resin. The grain orientation (parallel or cross-ply) of the strips bonded with either PF or UF had no significant effect on the glue bond quality when tested dry. In extreme wet conditions, the parallel-ply laminates were apparently more stable than the cross-ply laminates. Different parts of the bamboo culm significantly affect the resulting glue bond quality. In all conditions, laminates made from peripheral strips gave more stable products than those made either from inner strips or from the combination of both.","PeriodicalId":39305,"journal":{"name":"Journal of Bamboo and Rattan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87155715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bamboo shoot plantation area in this county increased from 2180 ha in 1982 to 20 000 ha in 2002; at the same time, the annual fresh shoot production increased from 7280 tons to 135 250 tons, annual fresh shoot production value increased from CNY 2.19 million to CNY 328.05 million (1 CNY = about US$ 0.12). The local industry development started from zero to 47 bamboo shoot processing enterprises, the processed bamboo shoot products amount to 114 000 tons per year. From these products, 32 180 tons are exported to international markets, with an export value of CNY 150 million. The annual per capita income of local farmers increased from less than CNY 800 to CNY 5100. This article introduces how the local farmers in Lin'an County developed the local bamboo shoot production from a natural autarkic economy to an dimensional and market-orientated industry. This progress involves Government supports, training for local farmers, construction of demonstration sites and establishment of technical service network and marketing development. This article provides a successful model for developing bamboo sectors in a community with poor conditions and achieves success in a comparatively short period of time.","PeriodicalId":39305,"journal":{"name":"Journal of Bamboo and Rattan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2003-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84231189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study revealed a whole variety of uses ranging from whole, round bamboo culms to parquet flooring. Most of the Guadua consumption is domestic and for household or construction uses. The export market is limited and mainly concentrated on bamboo poles for the construction sector in Peru. The largest potential markets seem to be national demands for the agricultural and construction sectors. Although there is some experience with the manufacturing and exportation of Guadua products, most actors involved along the chain present serious shortcomings in quality control and sustainability of the production. The growing interest in bamboo as an alternative natural product and the opening up of markets mean new opportunities for Ecuador, although much work has to be done on information gathering and promotion of Guadua as a new high quality product. The recent conformation of the National Consultative Council for Bamboo may lead to an increment of the interest in and competitiveness of the sector.","PeriodicalId":39305,"journal":{"name":"Journal of Bamboo and Rattan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2003-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83846111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the momentum of poverty alleviation in the developing countries has not kept pace with the population growth. This has serious implications on increased poverty in the regions. One of the visible indicators of the growing poverty is 'lack of shelter'. Reports reveal that millions of people live in hovel 'life- and health-threatening homes', simply due to their inability to afford the houses. This demands seriously to look for an alternative housing materials that are cheap, widely available and require less technical know-how. Bamboo has been found being an excellent building material due to its versatile characterises. It is estimated that more than a billion people live in bamboo houses, mostly in developing worlds. Additionally, its ecological and economical characteristics have made it a sustainable building material. In the past, bamboos were only used to build traditional hovel. However, it has gradually received an increased recognition as a building material. Few development organisations have initiated large-scale bamboo building programme to build houses for low to middle income groups. The projects were highly successful in achieving its main objective i.e. to provide shelter to poor families. This paper mainly deals with the successful stories of three housing projects using comparative assessments of cost and technical aspects. The ultimate objective of the paper is overview the applicability and market potentials of those housing projects for low-income groups in other regions of the world.","PeriodicalId":39305,"journal":{"name":"Journal of Bamboo and Rattan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2003-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82974774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
